I just picked these up Sunday morning from Mark Kenderdine (crimsonking). This line of Florida king was developed by another breeder from an odd looking kingsnake found (hit by a lawnmower) in Tampa, bred to other nice kings from Hillsborough county. The adults from this line look killer, though I'm told that they look their best before they're full sized. I'll post some more pics as these grow. Mark is the only guy I know of breeding these... Make sure and visit him at his table in Daytona this year, he'll have some great floridana, including some of the best hypo brooks I've seen.
Here's the male:

Love the head pattern...

And the female:


And for comparison, here's regular juvie king, might even be from around the same area:

And juvenile from the canefields:

Kinda plain in comparison, huh?
