I actually dont use the sit and climb as a sit and climb. I just use it like a normal hand climber. I can get over 4' of bite each time, w/ the climbing bar you'd probably only get 2'.

But i think thats the same w/ Summit.

One other thing, The LW is better on your knees than the Summit (according to my dad). You're pulling striaght up, not from the front bar like on the summits. My dad has terrible knees and that was the first thing he praised the stand for, it didnt hurt his knees cause its a more "natural" movement.
