We've had them for 3 years and I like them. The man I bought my heifers from has aged cows 14-15 yrs old so longevity seems to be there.
My husband has always had holstein/angus x's and this year he has said he really likes the calves out of our red poll bull. I've been really pleased with the purebred calves. We'll always have some cows no matter what and I plan on always having red poll (or at least a %).
They are good mommas, seem to be popular with grass fed, very docile. I got my bull from Jackson Farms in Indiana but if you go to the red poll site, you will find breeders in Arkansas.
