this might not be of much use, but the printing method i usually use could likely be nice for printing high key prints...... 'split grade' printing with variable contrast filters, there is surely stuff about it here somewhere.
i havnt seen your negatives, but i would start out getting an exposure with a #00 filter, lets say its 15secs, then throw in some #5 filter once you get a decent hilight tone with your #00, using the #5 to bring in the blacks....... lets say its 10 secs at #5 then, after you get a good mix between the #00 and #5 i might throw on a #1 or #2 for a few seconds to 'bring it all together'..... it seems to me this would be very usefull for such printing...
