Boy, it looks like the summit viper xls is the winner here today so far.....i love the viper, some guys say it has flaws with the bugee staps but i find them usefull, if your in good shape and dont have a belly to get in the way in bending down and strapping them over your feet you will be just fine. I have climbed some slick trees with it, and i even tried a telephone pole and it does the job!! Great stand.
