I'm still not a fan of the looks, but it looks okay with my Atomic which is what I currently use most.
I'm slightly concerned with the lack of vent holes. It's not air tight, but there is only a small bit of air that can get out through the switch. I haven't decided, but I might have someone drill holes in the larger tube for vents.
The locking mechanism is great! I did flip the locking ring around to spin the opposite direction. I'm a leftie and it's easier for me that way.
The switch is great too. Really smooth.
Thats something I've never even looked at, it really doesn't vent but through the switch and like you said, not much. Have you had to locktite those hex screws in the locking mechanism yet? After a few days I got tired of constantly backing them back out and bought some, no more loose lock ring
