I can only speak for my Scarlet, but I have to say mine is a bit squirly. Mine is a w/c Okeechobee locality specimen, and she was a bit tough to get started on f/t, however, once she took her first she became a f/t machine. In fact, when my other snakes refuse a meal, she plays cleanup (had 5 pinks in the last week alone!). Mine does not like to be handled, but will accept my infrequent "advances" after a few strikes doesn't scare me off. I wouldn't consider them a "showcase" animal because they are very secretive and mine basically only wanders out from her hide well after dark. However, she is my favorite snake because of her difficult personality!
My pueblan is only slightly more forgiving, but is still a very nervous snake. Mt Brooks is the most social animal (once he figures out I am not food!). His feeding response is ridiculous, but I wouldn't lable that as "nasty", but rather "easy". My neighborhood kids love him and he allows them to handle him without protest.
BTW, if looking to aquire a scarlet, someone on the Kentucky Reptile Expo forums (http://pub13.bravenet.com/forum/show.php?usernum=1033030719&cpv=1) gave me some good advice, and that was not to spend more than $50.00 for a w/c specimen because they can be difficult to start. Take that for what it's worth. I, however, wouldn't dream of parting with mine!
