If you are only going to run one, get the 1200...
I have two 925's and they work awesome.. I can listen to my 8000 watt stereo for more than two hours and still cranks fast when I go to start it..
I had the 1200 in my lightning.. it was a good battery.
my shop has had horrible luck with optimas.. they fail within a year..
odysseys' warranty is nice too
