These really aren't my favorite 3 bet bluffing hands. I might use them IP sometimes or vs someone who just folds shitloads vs 3 bets, but they flop so badly vs a calling range that I tend to reserve my 3 bet bluffs BB vs CO etc for Axs and other hands that are just way better, eg. Q9s. Blockers are nice, but vs someone that can and will defend some % IP, they make lame 3 bet bluff hands.
