Lewis and Clark Hazelnuts aka Filberts

Any opinions on the Lewis and Clark varieties Hazelnut trees from OSU?

Anyone growing them and if so, have you got to try the nuts yet?

I don’t know about those ones specifically but I have had mixed results from their hazelnuts in general. Theta, Tonda di Giffoni and another one seems to have been the only ones to live for me. The others can’t seem to handle our winters here in zone 5.
