Will I kill myself or my derailleur with the Rollerboys?
You'll struggle to notice. Ever since SIS became a thing, Shimano has rocked the Centeron-G jockey wheel (only the top one is called a jockey wheel BTW, the other is the tension pulley). This has taken the form of a slightly wider bushing than the pulley which has a metal insert for its own bushing in the cheap seats, the same deal in ceramic for 600/Ultegra, and a super fancy little ball bearing cartridge in Dura-Ace with built-in lateral slop (I guess it must be a pair of races of tiny balls for it to work).
Aftermarket replacements have made that all look silly by just having thinner teeth on the top pulley, or made it look even sillier still by not even bothering with a difference. I think Shimano must have decided back in the day it's an important component of SIS, helps the HyperGlide do its thing, and maybe it really did in the 6s days, but I've mucked around with eliminating it on 7s and up, and never noticed much change. I guess maybe it's a little more tolerant of bad adjustment, but I can't see how it won't inescapably make the chain less responsive to the RD.
I'm actually rocking narrow/wide 12/14t in my 11s Di2, and it's totally fine, probably a bit snappier than stock even (at the cost of a smaller correct adjustment window).

so so far away from accepting anything that even slightly deviates from their norms.
I hate that they’re so hateful, I hate that there’s a world view which is so hateful, so reductive, so insular. The obsession and identity with, and of, categorical black and white thinking. The dismissal of any idea, fact, or reason for nuance.
The idea that others are simply play things for their strict worldview.
Just fuck that, and fuck them
Amen, brother

I dunno, to my mind you've gotta be working pretty hard to consider that a bad thing. Omgios does a far less terrible job at PSAs than many...
I mean how about this brutal shit for triggering PTSD:

I posted a link to his mechanical watch page on a watch repair forum, where of course it was a repost, and in one of the earlier threads someone mentioned Bartosz hand-codes those animations in WebGL without using any libraries.
Someone needs to get this guy and pay all his bills and do all his life admin so he can spend 100% of his time busting out what he does best.

No sprocket distance dimension changes in the years between release ?
There was some funny business with 10s, IIRC... two versions, one with non-uniform spacing, was that it?
The arrival of 11s finally put a stop to worrying about anything beyond having the right number of cogs, didn't it? After all these years you can just throw in a Shimano wheel no problems.
That won't fool a trained eye for a second; any ti showing will give the game away in a heartbeat.
