Well, out of your collection, I'd say the BATB, TLK and Fantasia are most in need. The others have had a pretty good run on DVD and BD.
TLM could be useful for a lossless capture of it's sound mix, as the video is P&S, and the BD captures do look pretty damn good.
I want to say Cinderella and Pinocchio, but ww12345 and poita have purchased excellent film prints for both, which should be of reference quality once those projects are done with.
Also, could you put the using of LD color and BD luma in layman's terms? I'm not sure what you mean by that.
P.S, I noticed that someone bid on the incomplete BATB film print. Is it one of you guys?
