I went the other way, first gear was too high when loaded and off road so the clutch got a workout and I was never using 6th gear.
I still find myself setting my cruise control while still in 5th the 16t.
The 17t never stayed on bike long enough to do a fuel comparison.
I recently had a custom map built for my PCFC so I gained some HP and a heap of torque so I tried the 17t again, I only lasted a day before I put the 16t back on.

Club Lead not Club Med.
He with the most toys wins.
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.
