I picked up a Hybrid Pro/Rage a little while back and have used it at two or three track events now. Got a killer deal on it, $425 shipped on eBay (the guy claims it was unused, and it certainly looks brand new). Here's a few random observations:
--If you don't have a baller helmet (i.e. you're getting by with an entry-level Snell "M" rated helmet or similar, like me), it would probably be worth marking out the measurements for the post holes before you buy it. My helmet liner is not completely removable, and the nut/washers ended up having to go behind the hard foam piece that is not removable. Needless to say, it was a major PITA to get those things tucked back there and properly screwed down.
--The sizing charts on the website were pretty accurate. I measured out as being right on the borderline between XS and S (yeah, I'm puny
), and the Small I have is just a hair on the big side. So, I would trust those if you're not sure on size.
--The Hybrid Pro Rage is definitely belt-dependent, in that it's not going to do much if it's not clipped in to a harness. So if anyone is looking at this model thinking it will keep them safe in a car with OEM belts, I don't think that's the case.
--Once you get it adjusted properly, it's pretty easy to put on quickly. I just leave the whole thing attached to my helmet, then just pull the helmet on, put my arms through the arm holes, and clip the center buckle. Obviously this is easiest outside the car. The quick releases take some practice to hook up with the helmet on.
--I don't think I've ever even noticed the back piece, much less felt any discomfort. I'm also not using the seat pad with the cutout for the back piece in my car.
