I posted this yesterday, but it got lost (stupid phone).
I run my bolt snap free. I've never tried it secured in place, but my guess is it would make it more difficult to maneuver through the tighter passages. Typically, I keep my scooter in front and slightly below me, as I'm sure most do, but when I'm scootering in smaller, lower, tighter passage, the scooter goes off to the side and at the same depth as me. It would be near impossible to do this with a fixed bolt snap. With the loose snap, it just slides over and puts even tension on the line and the scooter. With a fixed snap, the tension would be uneven and probably cause the scooter to want to pull off to the right. This isn't a problem for large passage, but is definitely something to consider for sidemount divers.
Actually Rob it doesn't effect it at all, I run all my Mexico Gavins on a fixed snap and make lots of pretty long runs with it out beside me in the low ceiling caves. I run my OW scooters with a loose clip so I can do lots of stupid stuff, but for the really long runs I really like the fixed snap.
