I know Inzer has sizing guidelines for the LUP but I am also aware that some lifters are wearing a size smaller. Is there a reason for this? Do you get more out of a smaller size (tighter fit/carryover)? etc. Looking to purchase one and switch from my old Leviathian, I lift in 220 class but usually compete at 235-240. According to Inzer, I should be a 2XL. I am a 900+ squatter. Thanks
