Hi Ed, no I have not tried the Wabash or any cultivars. If the varieties are any better than some of the wild fruit that I have tasted then I will be thoroughly impressed. So far though I have only tasted the earlier fruit this season and I hope to get my teeth on some of the later season fruits.
I looked for Wabash while I was in Tn last week, at your recommendation, but could not find any trees for sale. I had to settle for Susquehannah, Shenandoah, NC-1 and two Allegheny. I already have two Mango, Prolific, Hillcrest and Sunflower. Those named varieties are at a property in Tn but have a few years before I can comment on the fruits.
