what topgunsteve says is a good idea, get an on one and ride it for 12-18 months seeing how you get on. I’ve ridden quite a bit round that area and a hardtail is probably the best bet, yes i know its nice to have 100-120mm travel but as a newbie thats what i would do. As for the weight thing i’m 15 1/2 stone and i’ve never considered my weight with buying kit, more depends how you ride etc.
On one, pair of rockshox pike’s on the front and away you go! :lol:
