going to 165 would require me losing like 30 lbs of muscle...pretty sure that won't help the wattage. (losing the additional 35 or so lbs of fat I have may tho )

+1 to those saying it takes a balance of losing fat but not power...and remeber you get to be good at climbing by sacrificing other things, which many consider more fun (flats and descents).

Also someone said something about "powering up" short climbs. This is very true, a heavyweight muscle bound guy with huge legs can make short work of a 2 km climb even if it is really steep, the weight loss is more and more clear as you do longer climbs.
