As you know cane borers are susceptible to my heirloom blackberries. Im joking but only somewhat! Little is not susceptible to my grandfathers favorite blackberry. The berries were passed down through the family over 100 years now until they are more wild than tame. They were named health berries not because of how healthy they are for us but rather how healthy the plants are! I spent 15 years improving the variety until they adapted fully to this area Blackberries by the gallons . I just helped the plants improve themselves by selecting the hardiest plants and making rows from the hardiest plant over and over. Most of the original plants i planted died. You can go back to growing those Mike if you need or want to but i suspect they do to well in river bottom soil. In heavy clay they seem to do the best often where nothing else grows they can reach 20 feet in height. My second favorite blackberry to the heirloom i grow is primeark45 which are exceptional. Have lots of hope 45s will fully adapt. I think 45 are the ones with the best genetics ive seen. Freedom does ok here and again im observing their growth habits hoping to someday make a cross of berries. They will adapt here in time.
