Yeah the Hammerhead G & I Cups definately get a vote from me, as do the kongs (particularly the larger ones)...Fisherman Big Mouth HP tail seems to sit down ok too
As Brandon has said, I have found that what makes an even bigger difference than the lure you are using in those conditions is the timing of when you work the lure, time it wrong and it will flip etc, time it right and you can still get a decent bloop out of a lot of poppers (Ebipops excluded, I just cannot seem to get these to stay in ther water in rough conditions)
