Without seeing your animals and knowing their frame size, their carrying capacity, their mothering and milk - to discuss bulls is almost an exercise in futility and a common topic here - that will often do nothing more than confuse the issue or at a minimum run you in circles and accomplish nothing.
As an example while maternal is important - in fact it might not be the thing you actually need. And in truth EPD's are simply a tool and not always as accurate as you might think - especially when applied to an uknown - ie - your girls.
To suggest a bull with even that minimum information is still very much like shooting in the dark - with luck you might hit something.
One final thing - remember this - runnning with the pack and using the "bull of the day" is often the worst thing you can do.
Somtimes - depending upon your animals - the bull that everyone loves will indeed work - but it can also turn into a disaster.
So - take a drive and look around and visit folks near by and ask them what they are doing. The benefit of this is you get to see the moms, you get to see the bull and you get to see the calves. And a big plus is you will get to meet a lot of folks that are able to provide on site ideas. Helps to join your local cattlemens association as well.
Call up a couple of local semen dealers - they will have catalogues of what is out there and available - plus pics and stats.
Put your location up on your profile - it helps to know where the person you're talking to comes from.
Best of luck - let us know how it goes
