Which breed-of-hamster is the best to breed?

what ever you want as long as they like each other but i like panda hamsters they're a really cool breed or a dalmation hamster

as long as its Russian dwarf hamster, I know someone who had baby Russian dwarfs and one or more squeezed through the bars of the cage and they never got them back. maybe is you had a plastic cage or a fish tank...it really depends on the environment you have.
