i don't know who the ppl you named are. But from what I am thinking you're talking about. I do both. I do the hop step and X when im trying to just go for distance on open fair ways....Actually I think I do it a little less on all normal throws too.
I used a Scissor Step, but today I went out and threw a round trying the pivot hop... On a hole that I usually have to rip to park, I over drove by by about 150 ft and off centered. I bogeyed coming back. I'm sticking to pivot hop
