Matt-

Yes the dropper does determine the height you'll be fishing off of the bottom. I sometimes change leader length as the tide starts to pull harder. At the beginning of the tide I'll run a 4-6" dropper and at the latter part of the tide when it gets to rippin I'll run a 10-12" dropper. The reason I do this is as the tide gets going harder the silt and sand starts to pick up on the bottom and rolls along. I don't beleive the fish like to travel in this and will elevate themselves above it. But doing the math with a 6" dropper and a size #6 spin glo I'd figure you're about 8-12" off the bottom when the tides going good. Remember plunking takes time, so be patient and the fish will come. Fish will also follow the current seams and as the tide pulls harder the current seams move closer to the shore line. So, sometimes you will catch fish closer to the shore as the tide gets to rolling along.
