Think Tank DSLR neck strap. Does the anti-slip work?

I've been looking all over for a new strap that isn't obtrusive or obvious and I really dig most of what Think Tank puts out.

Has anyone had any experience with their V2.0 straps? How does the anti-slip stuff work? Does it pull on your shirt? No shops any closer than 2 hours away so i can't go check them out in store without an all day trip.

I have the Speed Racer v2 and the strap is very nice and comfortable. I'm not sure if it shares the same strap with other v2 bags though? The straps padding has the perfect amount of rubber to keep the strap from slipping. I think it really depends on how much gear you carry whether the strap will pull on your shirt....otherwise I find the strap an improvement over the old.

I am interested too. Have used a Domke Gripper strap for years. Suggested that they should add gripper to both sides.
