I've never had issues with the md 12s I have, maybe I'm lucky but I've seen a lot of bodies and the ones I end up fixing wind problems on had a md on them.
What you do once you get a body is up to you, I was just sharing a tip on getting a body that has less film mileage on it. or I should say less winder mileage, I've seen people put the md on and play with the body with no film.
I have some pristine cameras that I baby. what can I say. I have everday users too.
Ummm, OK. I was just sharing my experience too. It is interesting to hear that your experience differs. Now the OP (and "SafetyBob") knows both sides of the coin. We work well together.
