RE: Summit viper
I love my viper also. The only input I can ad is that the rope that came with mine to tie the 2 pieces together had one of those metal crimped clamps on one end... to sort of keep it atached to the stand, this failled once when the lower part of the stand fell.... make sure you tie a knot to secure it to the 2 parts of your climber and do not rely on that crimp.
