i think that hoss would be simplest solution:it's tailored for big guys,bomb proof frame,26'' wheels are bit stiffer and weight less than 29'', you got great selection of rims and forks(xc, dh or similar rims n'stuff...),cost effective.and more efficient cycling on hardtail.definitely go hoss(hell, if i gain more weight than i should, ill' buy it as my next frame for sure)!
