I had to swap to my emergency brake pads for today's Edge Addicts event on the 3.1 at MSR (Hawk DTC-70), they are loud and too aggressive to use with RE71's (way too easy to hit ABS).
My group went out first, and the track was downright frigid which did not instill confidence. I didn't feel good until the end of the second session. I was about a second from my personal best, managing a 2:34.7 in the third session.
