That's awesome, sorry for naysaying the tccd50 months ago, I've never had good luck with them myself but I have one on the shelf to go on a za50 and I'm excited to give it another go.
For my money, taller gears and a airsal get you the same accel and torque with the higher top speed on a stock crank, but I certainly understand the appeal of a smooth running 50.
