There certainly are other options, and I'm sure others will chime in. But before you give up on the LW, have you followed the set up instructions from the dvd?
To get mine tight I use two straps, and get the stand hung. Then flip up the platform (while still standing on your steps), tighten the straps again as much as possible, and when you lower the platform it should lock the stand in with a lever action. Absolutely silent when done right. It does take some practice though.
Also, if you have an older stand, it may not have the offset bracket installed. The newer ones come that way, and make adapting to most leaning trees pretty easy. If yours doesn't have the offset bracket they can be added.
