The pressure placed on the touring risers is primarily down-force and hence a set of ski screws should be capable of accepting those forces. Pucks and touring brackets however have pressure exerted on them both up and down as well as side to side - which is why they call for a sturdier attachment system.

I wouldn't recommend using ski screws since they are darkly small, better would be to use some fat wood screws...
Personally I have been using heli coils for the risers and 2 of the 3 climbing bracket holes, then t nutting the center hole. This way its all easily removeable just in case, and much stronger than just screwed into the wood
i like aksltxlt's idea for just 2 t-bolts on the touring bracket, really, you probably dont even need the third hole drilled at all...
ive been working as a ski tech the better part of a decade, and have never seen a heel riser rip out of any ski...oh and they obviously use the ski screws, which are really just a wood screw with a different head on it.
ive also done the heli-coil deal and once we get the quiver killers in at my shop i will definatly try those out...

I have used ski screws for heel risers, and for Dynafit toe pieces for three years now with absolutely no problems. Properly installed ski screws can support tremendous loads in all directions. I have taken some pretty good split skiing falls on the Dynafit toe pieces with no problems. Perhaps if people are having problems with ski screws, they are installing them incorrectly? Certainly, there is no reason to T-Nut for heel risers, and remember, ever time you t-nut you reduce the overall strength and integrity of the board much more than a ski screw does at the same location.
