We have had hit and miss luck with the red bloods. Out of 3.2 Red blood pythons two of the males have been handfuls. Now granted both males came to us as yearlings, so they were probably someone elses problem child to begin with. We actually have a 6'6" 32 lb blood female that doesn't even strike her F/T dinner. She just crawls over and picks it up by its head and starts to swallow.

On the other hand we had a pair of STP's that were the devil incarnates. Got tagged by both several times. Again these were yearlings being sold by people that did not breed them.

I think bloods just need to be handled regularly from the time they hatch to have good personalities.
