I saw them at a deer classic. Although I favor Lone Wolf, the concept of the bar on the new Summit Cobra is a good idea. By swinging it above your head, you can still have the open front if so desired.

The climbing stirrups should work fine too. This past season, I never used my add on climbing straps on my Lone Wolf, I climbed the "Lone Wolf" way, with my feet under the braces. The Summit stirrups should work the same way.
