While I think YB's are a must-have in any collection I think it is very early to say the crystal ball is a YB x mojave.
From what Tom had said he is not sure what it is yet. His responce on an earlier post; "I will be finding out the possible genetics on this snake later this week, hopefully proving my theory"
Now lets use logic; if he had a YB and bred it to a mojave, why the wait? What is there to "find out"? I don't think that Tom is trying to buy time, for what? Is he running around buying up YB's as we speak? I don't think so. If it was as easy as YB, I think he would say that.
Not to mention, there are others with mojave x YB in the incubator now. If those are the genetics, we will all know very soon. (if not from Tom then by another breeder)
Sounds to me like Tom has some other things coming that will shed more light on the genetics. I think we should wait for him to figure out his new morph.
Until then we just wait... man, waiting for the breeding to start, waiting for eggs to drop, waiting for that LOOOONG 60 days, this whole industry is just about waiting. I hate to wait
