Need new batteries. Optima Blue tops???

I need two batteries to replace the Deka's in my '08 X-Star. I have access to two new Optima Blue tops. The only non-stock stereo equipment is two Wetsounds 485's and two Zapco 750 amps to run them. Would the blue tops be a good choice of batteries, or should I replace with two new Deka's? Thanks for your help.
