I've crashed (lowsided at +- 60mph, I think) with a HJC Cl-14, and ended up with a brain hemorrage. I don't remember the accident, so I can't be sure how the helmet faired (given the unknown circumstances). It appears that I went down very hard on my left side (head first, apparently), tumbled around a little bit, and slid a good ways on my face and belly. I'm glad I had a full face helmet on, but the HJC only barely saved me. Anyhow, I wear a Shark RSI now.
In the same accident, my Alpinestars Spinner leather jacket opened up, as the zipper dragged on the asphalt. I now wear a Dainese Zen leather jacket that "hides" the zipper in the button-up collar. I'm going to get a similar provision put on the Alpinestars when I get it repaired. Trust me, make sure that whatever jacket you wear has a safety catch of some kind to prevent the zipper from opening if you slide face down on the road. I lost a lot of skin (and some other tissue) because of this. After seeing the kind of damage my alpinestars jacket took, I will never wear textile or mesh again. Also, make sure you have CE armor on elbows, shoulders and back. I had and didn't break anything, although my left elbow was so swollen the paramedics (and ER doctors before seeing the x-rays) were sure that I had badly broken my arm.
My nameless, leather touring boots passed the test, but just barely. The left foot (the side I went down on), had worn a hole just above my toes. No damage to my foot, but this was a close call. I now wear Oxtar Replica boots.
I also had some Acerbis summer gloves on. These held up surprisingly well, but although the gloves are intact, I still managed to get road rash in my knucles (kinda defied the laws of physics on that one). I now wear N2 Kangaroo leather gloves (

Oh, and my jeans were completely useless. Not only did I lose skin (and whatnot), I nearly broke my patela. I now wear Icon knee guards under my jeans when commuting, and I'm seriously considering leather pants that zip up to my jacket for trips and other rides (I lost some skin on my lower back as well, and a jacket-pants combo would probably have prevented that).
Anyway, that's the best I can do for now. Sorry about the long reply, but I hope this helps.
Oh, and DEFINATELY get frame sliders for your bike. I had some and it kept my bike from being totaled.
And (almost over, I promisse) remember that expensive gear may cost more now, but hospital bills don't come cheap (and neither does a helicopter ride to the ER). A thousand on gear is nothing compared to 30,000 in medical bills.
Take care,
André
