Thanks for taking the time to reply

And yeah the Amazon listings are very convoluted. The cheap ones I saw had some reviews saying both plates aren't the same weight. Some were saying even though it's listed to fit in Olympic BBs, one plate didn't and they had to file them until it can.
Yeah that's true, gotta do what I gotta do and progress at my own rate instead of comparing to other lifters. I think a 15-20% deload with microloading is reasonable. I'm just unsure to just get the ankle weights or buy a set off Amazon despite the reviews (they're rating well, but I usually keep at eye on the bad ones too).
I already squeeze my glutes and keep my core tight when doing OHP; but my OHP is pretty weak. I get stuck with the weight slightly above my head.
