I always assumed both brands were made by Dave, since he and Jim are good friends and live in the same state?

good question but don't think so. both will getter done! i have one of the centaur heads jim send me to shoot all i can say is intimidating looking head and it flies great.

Ralph, After reading all the posts on the Simmons heads and seeing the number they do on deer I just ordered a pack of Tree Sharks as well. Fred

Hi Fred I also ordered some big game heads from Jim I always thought they wouldn't fly I was wrong Merry Christmas
