I finally had a chance to visit Truly Tropical on Thursday afternoon. The proprietor, Chris, is a lovely, charming woman.
I got to try a couple varieties that were new to me, and am looking forward to tasting a seedling variety they grow. It was also a chance to re-sample Pickering and Cogshall. So far, for me, Cogshall still has more flavor. It has that subacid undertone, beneath all the sweetness, that Jeff mentioned as being less noticeable in Pickering than in some others.
Har was there, helpful as always. I heard him mention that Zill's also has a fruit stand. I knew their nursery was strictly wholesale, so I had no idea they sold fruit to the public. I'm going to ask the Google where the fruit stand is.
