Activity code break craft 1.5.2 hack s

Long time listener, first time caller. I humbly ask the community for advice: after playing 1.5.2 on my long-term Minecraft world for... years now (time flies), and not even completing all there is in 1.5.2, originally planning to never update again, but now seeing the benefits lucky version 1.7.10 brings to the table, it is worthwhile to take the plunge to 1.7.10? My other options are to stay on 1.5.2, or update to a different version (1.6.4, 1.8.9, 10.10.2, 1.11.2, 1.12) that is not 1.7.10, but I am leaning towards 1.7.10 for many reasons.
My main reason for having the desire to go to 1.7.10 is the vast wealth of mods available for this version. Seriously it blows my mind, by some estimates there are THREE TIMES the mods available for 1.7.10 than any other version, going by the Not Enough Mods listing. 1000+, compared to the hundreds on other versions: older and newer. It's a whole different ballgame, an order of magnitude difference nothing else comes close to 1.7.10 and as a big fan of modded Minecraft I feel I am cheating myself if I don't play this version for real:

Version	Count (from NEM)
1.12	76
1.11.2	201
1.10.2	334
1.9.4	233
1.8.9	360
1.7.10	1205 (wow!!)
1.6.4	666
1.5.2	378
1.4.7	281

What do I give up from 1.5.2? Turns out, not much. I have about a 100 mods installed on 1.5.2 and after laboriously trawling through Curse and MCF and various sites I was able to track down updates or replacements for all but...two. Not that all mod from 1.5.2 ever was updated to 1.7.10, but of all the mods I was playing, 98% were. This is way better than I expected. The laggard mods for those curious are:

Mod	1.5.2 version	Last update?
Dartcraft	DartCraft Beta 0.1.18.jar	1.6.4
Legendary Beasts	Forge_LegendaryBeastsAlpha1.5.2.1.zip	1.6.4

which is not a big loss. I barely used Dartcraft, although I did enjoy it. And I beat all the bosses on Legendary Beasts. So I can survive the loss of these mods, although would nonetheless graciously accept advice on any other 1.7.10-compatible replacements for their features, if anyone has any tips.
The other big mod I used on 1.5.2 was MCPC+ which was amazing, expanding the server compatibility to plugins. I didn't need the server optimizations because I only play by myself and occasionally my buddy but having the option to expand the game by adding plugins was fun. I understand since then there are now more projects, Cauldron, KCauldron, Thermos, for 1.7.10 or later.
...or later. This infinite update treadmill has put me off updating in the past, but now that 98% of the mods I care about seemed to converge on 1.7.10 the planets aligned, but post-1.7.10 is in disarray by my judgement. Painstakingly gathering the "latest compatible version" for the 100 or so 1.5.2 mods I am using now, this is the result (approximate, this was only from a cursory search, but I believe it to be representative):

Latest version	% updated
1.5.2	1%
1.6.4	3%
1.7.10	45% (almost half!)
1.8.9	11%
1.10.2	14%
1.11.2	23%
1.12	0%

1.7.10 wins again! Nearly half of the mods I use today on 1.5.2 stopped updating at 1.7.10, there is no newer version available at least that I could find easily. Check out the distribution. Post-1.7.10 encompasses 47%, also nearly half. This means the modders are updating, about half are, but they stopped at disparate versions fracturing the ecosystem and inhibiting later versions from reaching critical mass.
I've read many theories why we reached a cliff at 1.7.10, probably all have some truth to them. A nonzero number of modders even made an explicit decision to stay on 1.7.10, for various reasons. Reika from RotaryCraft has an excellent thread on this topic in this subreddit. I also enjoy Immibis's mods, even though they don't get much love in FTB packs, they work well and I am familiar with their operation and they are all available up until 1.7.10.
Feed The Beast also has some excellent modpacks for 1.7.10, my impression is Feed The Beast Infinity Evolved (FTB:IE) may very well be the best all-around pack from FTB yet. If not the #1 best, at least among the top. For comparison I based my 1.5.2 world around Feed The Beast Unleashed and Unhinged. Built it from scratch, as I enjoy the meta-game of modpack creation, but inspired by both these packs and used most mods from them, except those I did not care for. Copiously used the Feed The Beast wiki, since I shared lots of its mods. And I blissfully played this game ignoring 1.6.4 and Feed The Beast Monster, the next kitchen-sink pack. And I ignored 1.7.10, until now, which is home to FTB:IE and Resurrection and other appealing non-FTB packs like Beyond Reality and Test Pack Please Ignore 2. IE in particular seems to have had the benefit of being introduced near the tail-end of 1.7.10 where mods have stabilized and content wrapped up. The change log on Curse shows FTB Infinity Evolved was updated to version 2.7.1 just yesterday!
I hear chatter about this month's latest Minecraft version release, 1.12, having the potential to become "the next 1.7.10". We will see, but the enormous conglomeration of content on 1.7.10 I can no longer afford to ignore. There are more modding tutorials also available for 1.7.10, maybe I'll try my hand at modding helping to expand this space further, contributing back to this community which has freely given us so much. Adding more fuel to this train with no brakes. If I do update, my plan is to stay on 1.7.10 indefinitely, keeping the same long-term world for years: but a new world from 1.5.2, because Applied Energistics to Applied Energistics 2 and GregTech 3 to GregTech 5 would break most of my base, it is too different, so I intend to keep a parallel server on 1.5.2 and start anew with 1.7.10, something I've never done before. And this is a great opportunity to remove mods I tired of in 1.5.2, though I have the option to re-add them since 98% (of mods I had) are ported to 1.7.10, but 1.7.10 adds tons of new mods, too. I am most salivating at the mouth for the realistic incarnations of industrial technologies in Immersive Engineering, the bases people post here are what gave me Fear of Missing Out (FOMO) and prompted this investigation into getting into 1.7.10. Of course, IE is updated to 1.11.2 but it also has a stable 1.7.10 version.
Long story short, my conclusion in updating from 1.5.2 to 1.7.10 is nearly all upside with minimal downside. I'll miss my old world but expect I'll enjoy the new mods more, and the added stability and new and exciting content.
In writing this post, I convinced myself, 1.7.10 is clearly the way to go. It seems so obvious with the facts clearly laid out. But I appreciate anyone's thoughts on the matter, any other pro's to 1.7.10 I must check out or unforeseen pitfalls with abandoning the shackles of 1.5.2.
P.S.: This post is 7000+ characters. What is it about the number seven?
