You sure?? I could swear that I have seen a flex frame with the paw instead of the JT logo.
Yes you have, but they are not 'Naughty Dog' frames no matter what some goober says in a PbN BST thread. They were made for Mad Dog Gear by JT. JT made prototypes in several of the HB colors, but Mad Dog rejected those colors and went with black and HB Grey. The HB colored ones are rare/prototypes.
