Another note on getting used to higher cadence; try shorter crankarms.
When I was racing 20+ years ago, I used to grind out the top gears with 172.5 or 175mm cranks.
Nowadays, I've got less strength, less flexible; still same height & inseam, but I use 170 or 165mm cranks.
Smaller pedaling circle I can spin smoother at higher cadence.
Seems to me 9 tooth gear would just wear out quicker, less tooth to share the load.
