I put a 15T Wee front sprocket on my Tiger and love it. I'm still getting better mileage than my friends who put the Arrow pipe on and Arrow map, even with the lower gearing! The extra RPM's in 6th make easy roll on passes without downshifting, too. I don't do a lot of interstate but a few times I have hit triple digits with no problem and plenty of RPMS left.
With the stock sprockets, 12MPH was the slowest I could go without pulling clutch in. It's much better now for off road, mountain climbing, etc.
