Just spent two weeks in the Swiss Alps running these and had a very good experience. They are warm and a little bulky, but protected very well during the one high-speed off into rocks that I had. We pedaled 4-8hr a day with me wearing them half the time. I'm 5'7 150 lbs (mostly leg muscle) and wear a Medium. My chick is 5'5 140 lbs and wears the same size.
I say great protection, but I haven't actually crashed my knee yet, but I am very confident these pads will suffice. Apart from going downhill, I have pedaled with them and they are super comfy. My only beef is that they're probably more than I need, but that's no fault of the pads themselves. I just mention it so you know these are beefy so prepare for the extra room if you need to haul them up. For reference, I do a fair amount of DH, but nothing super aggro, with a mix of XC riding. I would recommend these without reservation if you want a big pad without shin guards.
I recently bought these pads and I was also looking into getting the troy lees raid but I ended up getting these, best choice ever!! Ive used that under snow pants for snowboarding and my knees were completely fine and I also recently used them under my pants for ice skating due to the fact that I havent skated for over two years. I fell on knees with full force and I wasnt afraid at all to go as fast as I could and crash on my knees on the ice. I honestly didnt feel the hard ice which meant the pads were doing their job. I remember getting loads of bruises when I went ice skating two years ago and when I used the pads not a single bruise or scratch
