I've never grown any OP storage types, but I've grown Burpee's Long Keeper and Red October hybrids.
I wasn't impressed with Long Keeper's taste.
Red October kept for a long time (over a month and a half) and they held up very nicely...
maybe a little too nicely. Taste was also so-so, but still better than breaker stage harvested, ethylene gas (C2H4) ripened ones.
I'm hoping that Burpee/Monsanto didn't go dipping into the animal kingdom gene pool to create this one.
