William, I have some pretty mixed up corn carrying some genetics from Carol's Magic Manna, Cascade Ruby Gold and Cascade Cream Cap. Also a little from Joseph's Harmony grain corn is probably still in there. Those and a whole bunch of other "heirloom" stains represent about 50% and a worm resistant Mexican landrace called Zapalote Chico is the other 50%. I'm trying to push it more to a flint but have older generation seed that is more floury.
I don't know if cowpeas would grow for you but I also have a second generation mix that includes Carol's First Lady Northern Southern variety. I'm not really sure how easily cowpeas cross so if they don't Carol's would be the smaller, white seeds in the mix. Overall the grex leans toward a bushy habit but some do climb as well.
If you want some let me know in a pm. I don't really need any more seeds myself right now so a few bucks to cover postage would get you a good amount of seed.
