Gears & Axles - 3.90 Gears in an A4?

Hi guys,

I'm looking at getting a DSL 9", and it looks like my gears choices are either 3.70 or 3.90 gears. I have 3.73's now. I know 4.10's are too much for an A4. How about 3.90's?

For NA, 3.90s are fine. I doubt they'll be measurablely faster than 3.73s (or 3.70s).
