The skis I use probably the most in bounds have MFD's on them. This will be my third season on them, and I bought them used. I have done quite a few shorter tours on them and have been really pleased. It's super simple easy it is to switch in and out of tour mode, as well as change the risers with your pole ends, and you don't have to unclick. The hinge in the front of the MFD plate lets the ski pivot all the way around, allowing you to transition from up to down mode without unclicking. MFDs are heavy though, as mentioned. The skis I have them on are pretty light though, so it still doesn't feel like they have much swing weight, and I think they cut through stuff better than they would if they were featherweights.
Most importantly for me, they ski super solid. I have some Marker Barons on a different set of skis and they feel about the same. MFD plates + bindings, in some cases, is probably going to put you lower to the ski than Barons as well. Ive taken my MFD's on a fair number of park laps on the way back to the lot and they felt solid doing anything. I have never had any issues with the heel releasing while skiing or crashing.
