Not all snake skins are created equal...
I have a few Red Tail Boa skins that are as thick as Roo Rawhide.
And the Ball Python skin that found its way to PatB's place recently was pretty thick as well...
I have no data to back it up as of yet but I hope to test this very question in the near future...
But the bottom line is I Ain't No Boyer... so take my words with a grain of salt at this time...
