I've been using the Fastway 2" billet risers for about 4 years now. I really really love them because they just work and they never get tweaked or bent like some other risers I've used (I'm looking at you, Rox!). They are a little spendy as most Fastway gear is but it's built to last and last.
By the way, 2" is the most I can get out of my 2015 Husky FC450... any more and I'd need to extend cables.
