Interesting. I've not found any of the 3rd run C-lines to really ever be close to the truly beefy 1st runs, much less FB stability, but maybe you got a freak (no pun intended ).also after seeing Lizotte's in the bag (where he kicked out the firebird for a flat first run C-PD) I tried out this Pink board flat pearly very rigid C-PD that I actually gave up on and tried to sell at the marketplace.
My normal PD lineup is a beefy CPD that I can use like a FB (currently a Metal Flake CFR), my beat up shield stamp SPD that's my workhorse driver, and a beat PPD for hyzer flips and easy turnovers. Lately I've also been throwing a newer Freak stamp SPD or a 3rd run CPD in the bag just to have something a bit more overstable than my shield stamp.
