I just sold my big, heavy API Grand Slam. In the market for another climber. My 3 choices are the Lone Wolf Hand Climber, Summit Open Shot, and the Summit Specialist. I don't like bars in front of me. I like the size of the Lone Wolf platform. Like the seat of the specialist and the price of the Open Shot. Decisions decisions. They are all within a couple of pounds of each other, the heaviest being 17 lbs. Going from the 27 lb API, either should be fine in weight. The Lone Wolf has the biggest platform, but weighs more and is WAY more expensive.
