anybody knows how these 2 are different? i dont like gimmicks, actually i cant stand gimmicks, and also, i dont like carbon which i dont think is a gimmick but i dont like it, but I like high height for my steel so im debating between the old LS4 and what i think is the newer runner thats the closest to it, so im guessing its the Tuuk Lightspeed Pulse Edge. couldnt find much info online as to how these 2 are different or if one is just replacing the other
