Muskeez,
I am a big guy, 6'3", 245lbs.
The platform size is plenty big for me on the Summit stands. It measures 36" x 20" which is about 6" longer (out from the tree) than the Lone Wolf stands.
As I said in my reply above, I have the Viper but I would buy the Summit Cobra X4 if I were buying a new stand. It comes equiped with the foot rest, rapid climb stirrups and full body harness.
My brother is using his and loves it.
I saw the Cobra X4 on sale for $189.95 in the October Natchez shooters supplies catalog I got last week. That's $30 off regular price and their shipping is not unreasonable.
