I also took advantage of the 2 for 1 sale. I noticed that they are still listed on that website. Are you sure that they have quit making them? My only complaint with them was if you raced on a cool day, once the sun went down, the 60' was no longer consistent.
I will be going back to the M.T.'s next season, along with a set of SRD Assasins. I'm anxious to see how good the car will be hooking next year.
