The Raptor is a revamped boot for Head. The cuff is more upright, and the ramp angle has changed. It is based off the boot that Bode and the other Head athletes are skiing. For comparison, it is a bit more upright than my Head RD96, and I have a 3mm lifter on the toe for my RD's. It also has an adjustable spline angle, and can be straightened via screws by another 1-2 degrees (I haven't played with this feature). Other than that, it is a stripped down, bare-bones boot with the cool double-power strap and the bale-style buckles.
Fit-wise, this boot is almost identical to my RD96's, which have been streched in the toe by about 2mm. The Raptor feels more like 97 or 98mm in the forefoot: my foot fills up the footbet entirely. The heel is of similiar width to the old RD. It is very snug without being uncomfortable in any way (I have a C-width foot). I have a little less than 1 finger width behind my heel in a 25, and I wear a size 8/8.5 shoe. The calf is fairly narrow as well. The biggest difference over the old RD/RS is the slighly more forgiving forefoot.
Flex-wise, this boot is much, much softer than the old RD, which is known as a burly boot. The cuff is only about 1/2 as thick of plastic as the RD (which I had to soften considerably). Even after softening the RD (I thinned out the split tounge of the lower by at least 1/3, shaved the cuff down, and cut a huge V in the back of the boot) the new Raptor is about 5% softer. It was a perfect freeskiing flex, if not a little soft for the gates I ran. I will be using this boot exclusively on freeskiing days.
Responsiveness is equal to the RD, as would be expected. If I think "turn", I turn. There is no lag that I usually get in the consumer boots I have recently owned (XWave 10, Dolomite ProZ130). The boot goes wherever I ask it to, without questions or unneccesary bulkiness. As it is a fairly stripped-down boot, it feels light without being unstable.
The ramp and forward lean angles really worked for me on this boot. Out of the box, it skied noticeably better than my current RD, even though I have had work done to that boot to get my stance as neutral as possible (3mm toe lift, sole planing on R and L boot). I just felt very neutral in this boot: I am right on the cuff when I want to be, and can get my hips forward more naturally than in the old RD, which was my previous standard. I am able to get into the turn earlier and more powerfully than previously on my old boots, which made a huge difference in stability. Once I get dialed in with my bootfitter (Jim Mates of Seattle) I expect things to improve even more. I would prefer a bit more stiffness for running gates, but I will keep my RD's for that purpose. The Raptor 120's will be my everyday freeski boot.
