Crack resistant varieties

[jimtown]

I grew heirlooms for the first time this year with mixed results. My biggest problem was cracking. I did discover a few varieties that were very resistant to cracking( Thessaloniki, Eva Purple Ball ). Unfortunately for me , I found several more that seemed to have no resistance at all. I plan to try Kosovo, Aunt Ginny's Purple, and Aker's West Virginia since I've read that they are pretty much crackproof. I would appreciate any suggestions as to other varieties that are good in this regard. Thanks.
