I've had great results with Braille and XSPower AGM's. One XSPower worked great for over a decade, and a Braille lasted 12+ years.
CCA's are VERY misleading on AGM's, compared to a lead-acid. In my experiences, a quality AGM (not the AutoZone/O'Reilly "AGM") with about 400CCA will outperform a lead-acid of 1000CCA.
I've used the XS Power S925 and S975 with several larger inch street/strip motors, and they were more than powerful enough (and less than half the weight of a lead-acid). About the same cost as most lead-acids now, too.
Lithium looks interesting, but I'm happy with the AGMs at this point.
