I really like my Ray-vin. The legs don't lock down in place, but they don't flop around in the breeze either. The quick detach option is pretty sweet too. I've heard a lot of good about First Strike's scope head, but no one around my parts has one I don't think anyways.
And I'll echo the sentiment, Ray's a damn good guy to deal with too.
Edited to add: Both Ray Brandes from Ray-vin and Anna from First Strike post on Nationalmatch.us, you might be able to find more info there.
