Looks solid. How tight does it cam over? Compared to other platforms you have tried?

OOAL uses a totally different system. I get it rock solid, but I've seen where some complain that they struggle setting the Ridge Runners. A bit of experience helps with consistency, but it's not rocket science either. The XL has a longer post which probably helps stabilize it even better than the original.
While it isn't as basic as the LW style to set up, thanks to two vertical rows of teeth spanning the length of the post, it holds pretty well even when it's not perfectly set. I've heard it suggested that the platform should be set with the post having some spring, in other words, not fully rolled over flush to the tree. I don't subscribe to that, but weighted that way it's still unlikely to move.
I think most prefer the LW style platform cam action. It is simple and with some of the aggressive teeth on platform 'V's these days, cuts into a tree to aplomb. The Ridge Runners don't operate like that. There's a slight cam over of the post, and then bracketing of the tree (more similar to how a Millennium treestand receiver works actually).
I might even prefer the straightforwardness of a LW cam action, but still, I honestly don't feel it sets a platform any better than a properly set Ridge Runner. And the Ridge Runners seem to handle side and back pressure exceedingly well and will not fold up on you like LW style platforms could.
