Final Drive Ratio for 2 Up

HI,
I will be travelling 2 up to some of the rallies this year and was wondering what final drive ratio you would recommend. It is currently 4:8 on a 225 Rapido Classic, 30 Delly, 48 fresco and Indian GP 200 box. I was thinking going maybe 5:0 or 5:1? I also have a 48mm AF clubman I could put on, too. Thanks.
