I've found my success with climbers is almost none at all...b/c you need the straightest tree in the area which screws you multiple ways
But let's just list some negatives....

1)You have to hunt with respect to trees, then deer paths while it should be the other way around

2)Usually the tallest trees straight enough to climb are located in the middle of an empty area(because they never had to fight for light so they grew straight), resulting in a loss of cover

3)The closer to water you get the more trees tend to narrow at the top, resulting in a slipping or tilted climber.

4)Climbers have handle bars which are 1 more thing to worry about when the deer approaches.

5)Climbers are too comfortable, lol, seriously, they're hard to stand up from b/c those seats resist your momentum (maybe just me)

6)Climbers require trees with cleared bases...from experience my most successful trees have bases that are usually covered with thorn bushes, b/c the deer are coming out of the thick stuff.

My climber was the biggest waste of money I've spent to date...at least I got a saftey harness out of it. But if I was approaching an area I've never seen before, knowing I'd have to pick a tree out of the blue...I might go with a climber, b/c they're MUCH easier to carry and pack.
