I didn't make to the track today as planned, but I have new F1's as well, and so far they seem very slick to me...seem to come out of the hole OK, but on corners, they are still slippery...did yours do this, and do they get better after getting scuffed in...wish I had went late to the track to at least get a few runs in...I will try a local track next Wed night...but they usually require a helmet, which hasn't arrived yet...now back on subject, with my old tires just about shot and 90 degree heat, my best time was 12.61 ET, @ 110.86 MPH, 60 FT was 1.96 and reaction was .3100...so I am worried about the F1's hooking up, but I see you haven't had a tune, so that may be the big difference...just got to get back to the track I quess...nice work though...
