“ball grip is great for improving firearm strength, close grips are good, wide grip feels unnatural though. don't use all the bolts to mount, so I don't see a reason to have an offset of holes to mount symmetrically on the x3, I ordered a crossmember for my T3 so I will relocate. it'd be nice if the grips were a lite smaller in circumference. I have other pull up options so its ok, but if this is your only one, it could make regular pull ups annoying”
