Crank arm length

I've used everything from 165 to 175mm and I can tell the difference.

Really? Sitting on a bike with the seat adjusted for 165mm crank arms, you can't tell that there is restricted movement over the top of the pedal stroke when then using 175mm? Blimey. :roll:

Clearly not on the same bike. Only used 165 on the track. I used to us 175 on my road bikes but recently 172.5 which I have on three bikes.

The biomechanical sympathy argument for shorter cranks aside, I find it easier to pedal through corners with shorter cranks, and that is a good way to drop wheelsuckers off / gap any wannabe superhero types.
