Just a note on the Krymsk rootstocks - I've had fairly poor luck with 
viruses on them, I believe.  Most seem to take fine, but I lost the 
majority of the Krymsk-5 cherry grafts in 2010 and also the Krymsk-1 
plum and apricot grafts this year (lost the whole plant, not just the 
graft).  Might be worthwhile to order certified virus free scionwood if 
you'll be experimenting with these.
