had the 27.5 amp30's for a while and now on the new 29" pulse 30 and very happy with them. pretty sure i bought the very first set and usually i look for as many reviews as possible before buying something but with these guys i knew i couldn't go wrong.i usually feel flex quite quickly and was a bit worried going to a bigger wheel with less spokes but absolutely no issues. haven't really checked if the hubs differ but it has super fast pick up. also i run a xd driver so cant comment on that issue mentioned above....
