There is another thread right now about Predator pull away of the top standoff.
The reason for pull away is usually due to the strap not being perfectly level before the cam down...essentially the strap is not tight and not in a level position.
The same concept can happen with versa straps. When you hook the strap, you usually have 2 options for which loop...1 is tight and level and the other loop is not quite tight enough, but it kinda works. Sometimes the "right" loop is just a fraction of an inch too tight, so the other option is the next looser loop. Losing that inch or 2 can make a difference on how secure of a set you get.
There are a few techniques to address that. Twist the strap to essentially shorten it so the proper loop works, or wrap the strap around the post 1 or 2 times and then hook the loop.
Addressing strap tightness with versa straps can be done, but sometimes there is a fiddle factor.
Cam straps have less fiddling, but they have the weight and noise factor.
All this stuff has trade offs.
