I'm just not sure if I should keep gearing up from where I'm at.
Good luck at the Spektrum Race.
I run 33/72 on a 125' straight with the timing absolutely cranked up on the motor. I also run 29/72 on a 65' straight with the timing negative a touch on the motor to gain a little more bottom end when the straight speed isn't a factor. Hope this helps!
