I use TM and have used TM Pro. The reg TM is around 380 CA and 8-10 dkh ALK. But what I found with the Pro is that the CA is about 450 but the ALK was barely 6 DKH. Granted this is when the Pro first came out a year (or more ago) so they could have modified it and gotten it right. I prefer to adjust CA rather than buffer but have considered trying the pro again.
I know a couple of folks on here use Pro......
