Yes l can see the problems as well as the "advantages" (Inverted commas !) I have dealt with some lovely tame Sussex X cattle and had experience with some 'Loony Limmos' and l know which I would deal with. As for ease of calving on heifers we tended to stick with proven easy calving AA bulls ( After talking it over with Genus we avoided any N. American / Canadian bloodlines, no 'black Charolais' for us thank you very much ) But then we found that we had some really nice AA X heifers that we wanted to keep back for breeding but we were scratching our heads wondering what cross to put on those, which is why we tried a few Sussex, the resulting calves were lovely.It was done quite openly in decades past (I recall a blonde cross calf going through the pedigree sale ring, with some reference to grading up), but most pedigree/pure breeders have stepped back from it. Some commercial herds use a lim as a crossing bull on them, but carefully select out progeny.
There's a double muscled gene within the breed, and a lot of bulls are tested for it - many breeders don't want it due to calving issues.
My own experience of it was that I got the occasional calves really really stuck, and got rid of the bull responsible quickly, but that then, his daughters would throw up the odd one, usually with disastrous results.
As for behavioural traits...i'll stick with pure bred thanks.
