maybe, my home trails are hardpacked forest...mostly sand, hence the 2.1 @45 front
However, i do ride the trails on Blue Mountan, our local 800' "hill...mostly limestone, clay, with rock gardens and roots
here I use a bike with 1.95 Nevegals on Mavic 717's, but also @ 45 psi...I find that a stiffer sidewall works best in the rocks. My wife rides DH DDY rims with Kenda Megas at about 40...those wide tires offer more cushion, but I can only fit up to 2.3 in the fork and chain stays on this bike
I guess this is what makes life interesting
