Simple is not always good.X2...
While I climber may not work in every situation, it will in most. It simplifies things due to the fact that it's a way to climb the tree and hunt from. You can get really creative with climbers, as I have mine, making it into a frame, someone makes a kit to make it into a deer cart and you can even totes a saddle along to be used as a platform.
I think it will boil down to what your style of hunting is, what you goals are, how much weight you're willing to put up with and so on. That said you can become quite successful in a climber even though they arent the "next big thing" anymore!
Hell, if your interested in a climber, I even have an extra summit open shot that you and I can figure how to get it up to the great white north as cheaply as possible!
I know you and you are are serious guy and you require adequate stand sites to ensure an enjoyable hunt. Relying on a climber to allow a hunter to find and choose a tree that will put them in a spot that is reasonable for all the criteria a bow hunter needs is a huge challenge... finding that adequate, single tree that works can be the biggest challenge of the entire hunt.
For a new guy to hunting, or even a new guy to tree stand hunting, being in the right tree is more important than being in the "easy" tree. I know, from many seasons, that the easy tree can really suck when the deer are moving pats it 15 yards too far for a shot.
And you are not correct that a climber will work "in most" situations. You are a serious whitetail guy, do you really believe that? We just spent 2 full days in Iowa walking in patches (that are so good, that nobody in their right mind would walk away from) and seeing hundreds of trees that are TOTALLY unclimbable with a climber. Not trees that are just not quite perfect, I'm talking about a patch (that really HAS to be hunted) that could not be hunted, at all, if a guy used a climber.
Isn't one of the huge selling points of this entire site, the fact that saddles allow us to hunt almost anywhere? Our whole deal is all about getting away from climber crap.
