1.7 is great, what was your launch technique?
x2...............it's all about the 60' time and your trap speed to tell the difference. Every .1 you shave off of your 60'(launch) you'll drop about .15-.2 seconds at the end of the 1/4 mile.
Example
Joe ran a 13.1 @110 with a 2.1 60'(maybe some tire spin)
then he ran a 12.9 @109 with a 1.9 60'(decent grip with little to no spin)
Nice times either way and especially nice 1.7x 60'
