I think the sterlings and sterling bees are just something you do not see enough of. They are unique and very nice pairings in my opinion. I would go that route if I had a pewter male, besides Bees are just good in general to have around. There are a lot of different morphs you can make with a bee female if you get what you want with the pewter right away, you can switch her up the following season with another male to get some more interesting results.
I may beat you to it! I have two normal breeding weight females sitting in waiting for Sinatra to get up to weight. So fingers crossed if he keeps eating he may be ready in 6-8 months to be paired up. So if I get lucky I might come out with some beautiful lesser cinny babies in the next year-year and a half.
