Have you tested the gas mileage ?
On my Wee my mileage improved when I dropped a tooth from the front.
Until I dropped to a 16 on my V2 I never used 6th gear I also so never tested my mileage because from my first test ride I knew the 17 would be replaced.
I would much rather run a few extra RPM's than have my motor lug in the tough stuff and if you are carrying a load the 16 can only be a good thing.
So for me it is fit the 16 at home, leave the tools behind and enjoy the ride.

Out of my depth in a puddle.
Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
