i guess i'll answer the question. it seems like what you are after is something you don't have, you want to maximize chances by putting it in a lot of females, and don't want to wait 3 generations to eliminate the gene again. do you want one bull to service more than 40 cows, that might be steep. i think several breeds are in the midst of this decision. i think you should think about what you want to breed his offspring to, rather than worrying about him. you could breed polled half brother's to polled half sister's if you really thought this bull was something. you could even have those offspring tested for the gene and to minimze costs, whittle down the bull side to 3 or 4, both polled and horned, and test all the offspring cows, and repeat. the bull would have to have an awful lot to do that. i think you are in a catch 22, develope them polled offspring with more money later, or more money now with a polled bull, but slower progress down the road. then you could say do both, most don't have that luxury based on purebred average herd size. it seems like there is a shortage of homozygous polled bulls out there that are not angus and you would like to capitalize on that. i think of it this way, will you be able to cover costs with what you sell to a producer who must cover his costs to not dehorn. figure out what that is in your area, see if you have the time to go the long route for your debt service, vs the debt service of buying the polled one now and waiting for someone else to offer another polled bull. another alternative is just AI more for a short time, don't worry about the bull, just get one, and get a better one later with more decsion flexibility. perhaps there is a polled bull somewhere in a herd that has been used for two years you can get for the same price or less than the current polled one. which begs a question, do people do that? he would obviously need to be trich'd, then again, you would be introducing older genetics that someone else had already had, and he wouldn't be new, but again, what if you could get a better older bull than either of those original two. or do these bulls even exist without semen sales. seems like a tipping point in economics. you are battling breeding vs economics.
