I figured out what the problem is with the ratchets not locking completely secure. The ladder strap isn't thick enough. Even while locked the ladder strap is thin enough to allow the ratchet teeth to move up about half the height of the strap teeth. I just tried using a spacer made from some cardboard under the strap and it now locks as good as my NXT ratchets do. I'm going to find some adhesive vinyl to line the underside of the ladder straps to fix the issue.
Wiredsports, since you have direct contact with Flow I'm hoping you can make them aware of what I found so they can fix it.
