The width adjustable Euro pinch is a glorious exception.
The hand size vs body weight debate is boring. We all know that none of us will ever change our opinion on this topic lol.
I think its mainly thick rolling handles and wide blobs etc that give people with a large wrap an obvious advantage.
From my own experience of competing in many LGC competition the strongest competitor we have had has sub 8'' hands from memory but weighs over 300lbs (Martin Arildsson).
