Why should I NOT buy a IQ back and ditch my 4x5s?

Coming at this a different way - I've been shooting a MFDB for a few years, and very much enjoyed it. Managed to get a steal on a Leaf 40 mb back, totally happy. I have friends with the larger 80 mb back, but it has serious downstream requirements and is a bit too intense for this person.

Current thoughts are on how to get movements, still yearning for the joys of LF. An older 4x5 has been sitting for some time (film just seems to take too much time....which is short) , but the movements in LF are of course ideal. I've been pondering trying it with a stitching back for the Leaf, and see if the older lenses (58 and 90) can give enough satisfaction. General wisdom is not too positive, but maybe. The advantage of this is that the sliding back isn't too much (in the digital world at least), and can be reconfigured easily for different mounts.

High on the lust list is the Techno, with its ability to use simple lenses on lens boards, comprehensible movements and GG viewing. Maybe Techno, sliding back and Leaf back will make a nice combination, still with ability to shoot film. IQ180? While super nice, no real need to go there. Like Darr said, there is a lot of pleasure still to be found in using the older backs, and they are getting into the realm of affordable. While they may not match up at the extremes (thanks Tim!), there is a lot of good use to be found in them. They have helped me extend my work into more serious realms, getting closer every day to the carefulness of many of the posters on this forum. Getting there, still in progress!

Of course, today the 4x5 came out from slumber, with a 6x12 back, 120 film (easily loaded and processed) and maybe that's just good enough....
