Monte, what are the recommended tire warmer temps for the PR tires? Do the recommendations change based on PR 3/4/5 (compound)? And for a more general question, who has the chicken hawk pro-line warmers? I have a set of the standard, but I'm thinking of upgrading and I'm considering both the Pole position (2 or 3 temp settings) and Pro-line (completely adjustable). Any experience with either or both? And back to Monte, will one work better with the PR tires than the other? Thanks for the help guys.
