why not just buy a female/s? then you don't have to breed a bunch of females to him and pick one's you want.
you can breed her faster, see if she can raise a calf, and then get a calf out her faster than using semen.
that's what i did. probably cheaper and save time in the process.
there's no reason to get bothered about "limited edition", oops sooner semen not being available.
or else you could just buy some boomer semen, or buy a boomer female and not be stuck with bummer females and males.
don't see why people always seemed bothered by restricted semen.
