Concorde Battery: RG-35A vs. RG-35AXC

[BGFYankee]

So I'm looking at replacing the battery in the Lance, and I want to stick with a Concorde as I've just had better luck with them vs. Gill. For those that have them, what's the difference here between the -35A and the -35AXC? Seems to be that the AXC is a couple pounds heavier and has a higher amount of cold cranking amps for start. Is it worth the extra $20 or am I better off sticking with the -35A?
