there is a difference but i can't say what it was either, but it just seemed like i could feel a difference the races were very close but fun wish you had been there that would have been 3 big bore ds's and oh 1 sparks raptor that was close.

 

My 770 & 720 are very close. We raced all weekend & it was a crap shoot every time. The start could make the difference!!!

 

 

Look at tvipowerandsports.com. Click on DS Works. Thats the stuff and more.

Enjoy.
