I do as well, although have precious little free time these days to shoot either.
I got into the Hy6 system about 7 years ago, and still think it is a great system that was all but abandoned by those who created it. I shoot whatever slide, negative, or b&w film I can get my hands on through it, and when I want digital, the Credo 80 back produces the most stunning images coupled with all of the Schneider glass that make up the Hy6 ecosystem. Just like the music industry, I think we will see a resurgence of film in the photography industry - we went from vinyl, to tape / vinyl, to CD, then all sorts of weird pseudo recordable digital formats (DAT, MD, DCC, ADAT, etc), then pure digital (MP3, AAC, FLAC), and now, after all of these years, wouldn't you know it, but the vinyl market has been _growing_ these past few years, while CD sales shrivel up. And tape is even making a comeback in some niche areas too.
I'm going to sit tight and hold on to all of my Hy6 gear - shoot it, care for it, and hopefully one day, make some money off of it in the form of sales to clients who want an artistic look with film, alongside the purity of a digital capture.
