I have actually been really lucky with them. So far I hit 3 out of 4 on the 50% PH lavenders, 2/3 on the 66% caramels, and 3/5 on my 50% ph clowns. The only one that it has not worked out for was my PH G-stripes.
I bought a Het G-stripe male back when they were still a lot of money. Paid 1k for my het male. I made three poss het females with him and so far it looks like none are going to prove out. I am giving them all one more year before giving up on the project.
