I ordered 1 of each this past spring and they have been great layers and very friendly. I wish I had 2 of each. As far as Mcmurray goes they were great also.
You can fly rollers in club,national and world competitions. They are probably just as easy to train as homers. And don't think that they don't like their flying time. You wouldn't want to be in front of the kit box when the door opens. I'm thinking you spend alot of time training your birds...
