Does anyone have experience with the low angle pocket holes produced by machines such as the Castle TSM-12 or similar?

I'm interested to know if the 6 degree angle causes any problems when driving screws, particularly clearance for the drill chuck.

I like the idea of the clean routed pockets, and the touted advantage of minimising joint slipping while driving screws .
