Don't focus on ratio, at least look at gear inches or how far the bike moves for one pedal revolution: Sheldon Brown's Bicycle Gear Calculator

Sounds like you have mid 80's gear inches, which is a bunch. Dropping your ratio back to give mid 70's would probably be better. I'm running 42x16 and with my tires get about 70 gear inches which works when I have to go up some of the hills around here.
