I'm having similar feels with my comps. Disregard comps, acquire gains.I'm planning to do a classic class next year in maybe a small organisation. It's full on off season this year which is what I needed. I've made some great size gains from it, notably on my back and shoulders, two areas I really needed to bring up
I miss competing so much, but it's one of those things I didn't want to do for the sake of it and not be happy with the result
Straps don't stop you holding on to the bar tight, they just remove the necessity of being able to support the weight for the whole rep. Shouldn't affect your set up.
