Your going to be in the market for a cranking battery, bro. Must also charge between trips. Check the battery thread pinned up top here. I've had good luck with Dual Pro/Northstar AGM's. Unfortunately they are no longer available. The Cabela AGM's have identical spec's. Have also heard good reviews on the Die Hard Platinum AGM. Get the group 27's at a minimum. The 30-31's will provide additional peace of mind since you tournament types run your pumps and electronics more than I do. As if you haven't spent enough $$ on that baby lately!!
