I just purchased a Summit Goliath stand.

The advantage of the Viper and Goliath as well as some other Summit models is that they don't have any moving parts to make noise. You just put the cable around the tree and that's it - no parts, knobs, screws, toggle bolts, etc.

I'm sure all the Summit stands are good and better than most.

I'm 260#s and I need the additional size of the Goliath. At 170#s, the Goliath would be great if you hunt when its very cold and you're packing thick layers of clothing. In this case, the Goliath would make it very easy to transition from sitting to standing and vice-versa.

Good luck with your choice.
