I know this is an old post, but being new to the board thought I'd chime in on the ol' Voyles' Little John blood, as Frosty said they are solid. I to haven't seen any of the Stryker stuff I'd feed but I know there must have been some out there worth something to some folks. I've been happy with what I've been able to perpetuate with the blood over the last 13 years.
