I have some trees on Krymsk 1 that are about five years old.  It has been 
doing fine but I would say more than 50% dwarfing if anything - it is a 
serious size reducer and its been hard for me to adapt to since I am not used 
to so much dwarfing in stone fruits.  I have only used it on apricots and 
plums.
