Yes, yes! It is a fine line between spinning too much and mashing on a hill. Spinning in too high a cadence can just burn needless energy. If you mtbike, you learn real fast that you can also loose momentum and traction. With 4 knee ops, I have really stay focused on that small area between abusing my knees from too hard a gear but also just burning out from too high a cadence.

Congrats on finding that very thin line!
