Great info guys!
I've been running some 17.5 TC on a medium/large asphalt track the past 2 months. I started with similar settings to what I ran inside and found the timing to be a bit too high. Temps were higher than I'd like and fade was an issue. I've been backing off of the timing and adding more gear and that seems to be helping on both fronts. Currently at 45* on the motolyser and 3.9 FDR. Working my way towards trying a low timing/high gearing setup soon, hopefully this weekend.
Congrats Aaron on your new personal best!
