[NAFEX] peach leaf curl/resistance

Most of my peaches are seedling Siberian C peaches from Bear Creek.   
Some trees have no leaf curl & one or two have it pretty severe.  Is  
it possible that resistence varies from tree to tree or is it a  
matter of time before they all get hit bad?   Would cutting out the  
heavily hit trees be a good idea?  My one observation seems to be  
that the trees that are more in the open, more sunlight & airflow,  
are looking much better.
