Well, I went in as a street CA for them a while back and the B-190 was just straight ATP mins as you have to have an ATP to be a CA. The dash I think fell under ICAO mins which would require the extra PIC time.
One thing to think about though is the extreme likelyhood of getting violated as a New 121 guy and a CA. I took that route and it almost gave me ulcers. I got out clean but some other I worked with didn't. Something to think about. Remember Mesa has the FAA on speed dial for turning ppl in.
