RE: 6'8" tall 325lbs, looking for a climber.
I'm 6'10" about 350 and I use a Summit Goliath. Awesome stand, very sturdy, very roomy. Definitely going to be the one you want. Lone Wolf is rated to 350, but uncomfortable as hell. They have a new one this year though too, Summit 180 Max, even bigger than the Goliath, definitely worth a look.
