Ash, If i was you i would consider possibly running a 7.5 or stick with the 6.5 and don't use full power and work on your lines more as this is where most of the time is made. I think in my second run i was only using full power in about 3 places, mainly cus it was quite close in our heat and i posted my fastest of the day.
Jase, nah i can't beleave it we have finally got you to stick to one car
