Hands down, Lone Wolf. Its the safest because of the sinch down straps. As soon as you use one in a tree you will understand. Also because of the straps you will not be able to knock down the top if you hit it or bump it when standing or sitting down. Its real quiet in the tree, its quiet carrying in if you put it together wright. And its light. If you are phisically restricted, or over 50, get the sit down climber. The negative is it's the most expensive. You get what you pay for.
