Sorry, I dug up an ancient thread :sad: ... I believe Swiftks recommended the LMJT not because of the metal jacket, but because it is "left positive", which can only be purchased on the LMJT version of the 1200, and matches the OEM battery. Not saying you can't flip it around or whatever, but the LMJT is probably the safest advice.
Actually Todd, this is probably a good time to rekindle this thread. Winter is coming on and we all need access our battery's condition. During the spring, summer, and fall we are all obsessed 'more power,' traction and suspension, swag, and other things to impress our buddies and the fairer sex. But winter is when a lot of us really "need" our machines to perform, especially north of the Mason-Dixon! A Duraclutch, Bikeman-RVS-Empire setup, dual 50" lightbars, 31" Outlaws, and double overhead cam windshield wipers, all don't mean squat if you can't get your machine started! If your livelihood or safety depends on being able to clear snow, don't overlook or skimp on your battery. Odyssey's may be overkill for some, but the piece of mind is priceless--heck, I run dual Odyssey's in both of machines and I don't even get (hardly any) snow! A good quality AGM battery is often the difference between having a dependable machine or $14K, 1500 pound paper weight.
One correction, the Odyssey 1200 is available with a left positive terminal without having to buy the metal jacket version (#0766-2027BONO).
