I've been doing ok with a 6XD but I'm still learning how to find them deep. Mainly slot fish but I did have an over.
Note I haven't had much trouble with the pleasure boaters as I have fishermen. I'm not sure what the deal is but everytime I'm on a main lake point boats have been on plane driving straight between me and the point. I don't see why they would drive straight over the spot I'm fishing when the entire lake is behind me to go around. I have more patience with the pleasure boaters because I would expect another angler to have respect for other anglers...
The pleasure boaters and jet ski's always go between me and the bank, no matter how far off the bank I am fishing. There can be a wide open lake behind me, but they never go behind me.
