Need Vortech pulley suggestions for Vette.

I recently bought a Vortech S trim. It's going on my '04 MN6 Z51 vert. The car has '03 Z06 243 ported heads, Lingenfelter blower cam, FLP longtubes with HF cats. I drive about 10,000 miles/year for pleasure. I don't race, but play on the back roads. I'm getting it with the lowest boost pulley (6 lbs with these heads). I also have first shot to buy other pulleys at a good discount. Any suggestions from experienced Vortech owners? I'm looking to not push things so far that I blow stuff up. (Really)

2.95 pulley will give you another 2-3 lbs. gotta make sure you retune everytime you change pulley size. have fun!

By the way my car is a daily driver and it seems to be holding up well. I have owned it for 2.5 years now.
