As an owner of four past sleds that had powder pros, I can say this I have used various brands of non SLP carbides on my sleds. My last sled I sold this fall, realized the left one was worn to nothing I put a new one on and found that the second set of nuts they give you to hold the ski together if the carbide runner breaks off did its job! The key to using any set of carbides on these skis is to use the thin nuts on the center bolts. Have had these on all of my past sleds and most likely will put on my new one as well.
