Recommendation? Blasting media for TI scales

[slashfuzzle]

I'm picking up a blasting cabinet and trying to determine the right media for my TI folder scales. I'd like a dark gray more 'user' finish (vs something more satin or polished). What grit AO would you guys use?

Thanks!

I have shot my sebenza with 90 psi and fresh glass beads and it's only a touch less rough than factory. Can't even tell when not right next to a factory sebenza
