Somebody's talking crap here & it ain't the tree!
I have both 6 and 10 ply full wraps, the 10 ply gets used in the arena only for the speed races (to hot for the rips). I have read a number of threads where people have reckon more is better on the layers, to many cons I reckon with wearing them in a work environment, ie heat exhaustion and decreased mobility. Price wise they cannot be beaten.
I also heard from a guy in Europe that square ground chain is illegal to sell over there because it will go through chaps a lot easier than round ground. He was importing square ground from the US.
From what I've heard he was actually correct as even though Stihl make RSLK in Europe they can't sell it there.
