I cant really give u any info on hogs but I do have a red tail and she is an amazing snake and very friendly as well as very active, however another option u might want to look into a Nicaraguan boa. I have one of them as well and I heard they r a bit nippy as babies however, I have had no issues with that. He is extremely docile and friendly even. Nice stay on the smaller side as well averaging 4 to 5 feet, but no matter what u pic u will be happy with one of these choices.
