Greener Grass phenomenon.
I have a climber, and I bought a LW hang on with sticks because it will weigh the same, and open up so many more options for getting into better trees than my climber.
Honestly, time wise, it's pretty much a wash for me. From ground to in the stand and hunting, the time is pretty much even. I feel like the climber is actually nosier than the hang on getting setup overall.
It's worth having both IMO. If I'm going in somewhere 100% blind, I always take the hang on with sticks. I know i'll be able to find a tree to get it in. If I'm going somewhere I know, or it's the afternoon going in blind, I'll usually take the climber...I can shoot out of my climber while getting up the tree...this is not so with the hang on.
I'm not a big fan of Summit climbers. They're too bulky on the back for me. I really like the way LW climbers pack up and sit very close to your back. Summit is a bit more comfortable, but I've done numerous all day sits in my sit-n-climb without issue. As far as a shooting rail, they're not for me. They got in my way every single time I used one with a bow.
The key to shitting out of a tree stand is using your harness...You DO Wear a harness right?
