Seeking genetic diversity:

I'd like to know if there is any interest in exchanging queens for future breeder stock and / or drone mothers. I'm in central lower Michigan, and I'm particularaly interested in trading queens reared THIS year from strong, overwintered (absolute must) and un-medicated (highly preffered) NORTHERN (another must) stock. Race of bee is not critical. I have mostly italian / carniolan crosses.
My first batch of nice looking tiger-tails (bronze & black or gold & black stripes on queen's abdomen) hatched this week and hopefully the mating weather early next week will be good.
