I've had a bunch of climbers and now am using old API Shoot'n Star, old Summit open front, new Summit Open Shot, Equalizer and Lone Wolf Hand Climber.
I like the Lone Wolf Hand Climber best for my use. I hunt with 64" recurve and get the best clearance all around with the Lone Wolf. It's the quietest, most sturdy in the tree, packs together faster, lightest to carry and goes on the smallest trees. However, it doesn't do good on trees with a fast tapper from big at base to smaller and will not work on bigger size trees. The Equalizer works best on all different size trees..has more adjustably and the Summits won't work on smaller trees. The old API is heavy.
