The Force mills are known for running a bit hot, but well within safe zones. My Force .26 liked to run 270 deg, but as long as you have a good smoke trail, it wont be a problem. I used a couple different pipes on it, and the JP-1 actually seemed to be the best, even though its a low TQ pipe, but I ran on a tight track.
As for HSP, I can't help ya there, I dont know the brand.
