I was actually at the PSA meeting, guess I should have taken notes. I figured it was the hole size while on the water too, since they were getting clogged up. I was just redrilling some of the holes to 1/4" right before I read your post.

I was setting anywhere between 200' - 350' deep trying to find shrimp throughout the day, mostly around 250'.

Several people told me that it was hot early morning, and died down pretty dramatically, so go early tomorrow! I may be out there if I don't feel so sore...

My boat is an unnamed 22' Grady.
