RE: Question on climbing treestands
smokepole,
I think since the Summit Bullet and Broadhead both fold flat they will be less noticeable on your back. I have found that adding a set of padded backpack straps helps eliminate the pressure on your shoulders. Another thing I do when hiking a long distance is tie straps to the stand and then around my hips. This puts the bulk of the stands' weight on your hips instead of your shoulders.
Once you get the stand you can adjust the seat cushion and the climbing platform and almost eliminate the problem of the bar getting in the way. Another benefit of the Summit I forgot to mention is the safety harness that is included with the stand.
By the way, I like joeturse' s idea of buying both climbing sections!
