I had the Viper and im 6'4 250lbs and while it was the most comfy stand up to that point,I could of used the extra room..SO i sold it and paid $305 out the door for the Summit Titan and that has got to be the best $300 I have ever spent..Its identical to the viper,but just bigger and has more room..Its nothing to be able to sit all day in this thing,its truly like a lazy boy in a tree...Some people will skimp when it comes to a climbing stand,but when you do,you skimp on comfort and saftey..The summit climber grip the tree like no other,it actually diggs into it,when Im ready to climb down,I have to actually pull the stand out of the tree...Don't hesitate to spend some money on a good stand..And just FYI,never leave it in the woods,thats the best way to not get it stolen..I'll never leave my Titan in the woods by itself..
