Being heavy due to overbuilt construction (6 years semi pro swimming team) helps me however to put good power through pedals and to be able to resolve trailside conflicts (with ******** anti-cyclistic walkers) with ease .
I'm not sure if I should be offended as a trail access advocate or as an employee of the board of mental *********** and developmental disabilities. Since both mountainbiking and people skills are more about finesse and technique, I'd discount your burly strength as anything positive in either situation.
As for my on-topic comment, also look in to an aftermarket brake arch for the fork to supliment the existing one built in to your fork. I use an old one from a set of magura hydro rim brakes and it works well for me.
