I hope you don't have to go through as many to find your next spike as I had to to find mohawk. smile I didn't think he was ever going to come along. I chose mohawk since you are experimenting with spike already. I'm already certain of the babies they can produce though. It will be the last six heads...unless I'm dead wrong about this, and I don't think I am. I have a family in all five slots with one being a 10th gen, so I'm pretty much certain about how VF genetics works from them.
