I don't think the overall effect on aggression should be too drastic assuming you very often can't protect your hand because you should be pumping draws mush more often w/ 5+ players in the pot. Your equity will more often be higher than your fair share.

Because pumping is done by raising or betting, not by calling your AF shouldn't be too terribly different, i think.

Also, though i don't often practice this myself, seat selection could help protect your hand if you can sit behind an aggressive player who likes to bet/raise flops. this will allow you to raise your made hands and face the field with two cold, which should help, from time to time.

What is your AF? How many hands? thanks. . . good luck
