I am not really a climber guy, in fact I hate them. But I do have the LW sit & Climb and Hand climber. I originally had the old seat for LW and now have the new seat and will say I love the stand with the new seat. It packs together nice and tight, is light, quiet and very comfortable to sit in. I really like how there are no pins to drop. I am not sure what the new summits are like, but hear good things about them as well. I doubt you could go wrong with either.
I have all the stands sitting there in the garage, but 99% of the time I grab the LW Alpha hang on and sticks. I have a heck of a time finding climber trees, and if you do find a good one, 9 times out of 10 its not where you need to be. I see so many guys limiting theirselves by hunting out of climbers. Plus I can actually get up a tree just as fast with a hang on as a climber. I am not that graceful with a climber.
If you have a good piece of property with alot of good climber trees then that will be the ticket for yah!!! Goodluck choosing one, Gunrunr will set yah up!!!
