All of the above mentioned are the ones I'd recommend. The Optima's will save some weight as well. Also, the sears diehard marine platinums are made by odyssey. Same battery, $100 cheaper with 1 year less warranty than the odyssey, but still 3 years free replacement. FWIW, I have a Odyssey cranker and 2 Optima D31M trollers (24 volt troller).
