I've used 15/45 there and 15/46. I liked the 15/45 better. Avg time was 1:05-1:06 with a 1:04 as best lap time.
I ran stock (becuase I didnt have a chain for my sprocket kits) and ran 1:03's Only used two gears though :lol: I think it was 2nd thru T-1 up one, down one for the bowl.... hold that to the back stretch, up one then down one for the chicane. Up one then down one for t-1
