A4 3.73 Vs 4.10 gear swap

[fullforce]

Anyone running 4.10 gears in an A4?
My pinon seal has been leaking and getting worse and now since my car is shifting into 3rd before the end of the 1/8th mile now I have been thinking of just swapping gears. Ive read alot about 3.73's and people say dont go 4.10's because it will be screaming on the interstate but I have never even had my car on the interstate and run in 3rd gear probably 75% of the time anyways since Im on backroads all the time. And obviously Im sure 4.10's would weaken the rear more than 3.73's?
I do plan to add more power later but by then Ill need a stronger rear anyways, just looking to get all I can out of a gear swap as possible.
Thanks
