TTK, regarding sliders... Plastic sliders become quite brittle in cool temps. it's all a crap-shoot anyway!
D_T, hope you heal quickly! neosporen or Bach rescue remedy.....

Try these sliders out.

They are what I went with and about 2 weeks or so after installing them, they got a test run of about a 100 ft. slide after the left side of the bike was slammed down. Worked perfectly!
As it states here as part of Motovations selling point:

Fasteners
We use mostly 12.9 grade (176,000 psi tensile strength) hardened steel socket head cap screws for our slider to frame attachments. Most socket head cap screws of this type are supplied for use as flywheel or connecting rod bolts. Our choice of bolts for this mounting configuration is so that they will bend instead of snapping when subjected to excessive stresses. They are almost always supplied in black finish but we take the extra step of having them galvanized for better corrosion resistance. This may affect their exact thread tolerances in some cases. Another thing we've been asked this a lot: "Why socket heads instead of standard hex headed bolts?" The answer is simple. A bolt fits into a hole in the slider. To tighten that bolt you will need a hex drive or a socket drive. If you use a socket because it's a hex head bolt, the hole in the slider needs to be bigger to accommodate the size of the socket, requiring the slider puck to either be bigger overall, or thinner walled. Hex drives are smaller profiled and therefore need a much smaller hole in the slider for the drive to be inserted. Socket head bolts are also much harder to come by, especially in metric and non-standard pitch configurations. They are considerably more expensive, but we feel that they are a worthwhile expense. We do not use hex head screws, only socket heads and they are all either galvanized or stainless steel. Never black oxide coated.
We also use stainless steel socket head cap screws for attaching sliders to brackets (in street no cut model frame sliders kits). Usually they are of Grade A2 (304) stainless steel with a tensile strength of about 101,000 psi. This type of fastener was chosen as they are meant to snap off on excessive impact before transferring that excessive force to the brackets which would amplify the forces to the mounting points on the frame.
Washers: We only use 304 grade stainless steel in all our slider kits to reduce metal to metal corrosion and binding.
Frame Slider Material
Motovation Accessories uses a proprietary High Molecular Density (HMD) formulation of nylon. This nylon is impregnated during the extrusion process with UV inhibitors to resist destabilization of the molecular matrix and discoloration during prolonged UV exposure. This formulation is also molybdenum disulfide infused to give it the same lubricating properties as Delrin. This formulation is 75% more resistant to abrasion than Delrin and exhibits a reduced propensity to "chunk off" or "break off" during extended abrasive events and it's 'slickness' reduces it 'grabby-ness' during slides that may cause your bike to tumble and cause more damage.
What about Delrin or ABS?
Many frame slider manufacturers use them because it much softer, much cheaper and easier to machine, i.e. the material flakes off readily in a lathe and is much easier on the tools. The reason why Delrin is easier to work with therefore makes it a much less suitable choice than our selection for frame slider material. Notice in the pictures on the left that our material shows stringy edges at the point of abrasion. Delrin does not do this. It chunks and breaks off on impact much more readily. Furthermore, Delrin is not UV stabilized and will discolor or grey in sunlight which will further downgrade it's structural strength.
In any case, I'm glad to hear you are doing better and didn't get hurt worse.

Since then it's been Intuitive or nothing for me (though I may give the Woodcraft ones a try, as they're solid pucks that mount to a fixed post... interesting concept!)
