Sometime ago Mike Jolliff was selling some snow project animals that did carry genes for two different lines of Axanthics. I don't remember which two lines, but obviously one of the linesw was the Jolliff line. By the way, there are five different proven lines that I know of: VPI, TSK, Jolliff, NERD and D&M. From what I have heard the D&M line and the TSK line are compatible. However, I have never actually seen the results of the breeding of the two lines together.
