You guys obsess over cameras and film size way too much. You use whatever camera gets you the shot you need. The end.
Ultimate print quality is a secondary consideration, after you make sure you get the shot AND something that is interesting and worthwhile.
I agree, use the best tool for the job at hand. I like using my 35mm slr. I wouldn't mind getting Leica M6 or M7 with 2 lenses. But that will have to wait a long while.
I also wouldn't mind getting Pentax 67 to go along with my hasselblad. But for now I'm pretty happy with what I have.
