170cca is adequate for what that battery is designed for, and thats powersports applications like motorcycles, ATVs, etc. Also since most guys started using "mini-starters" has anyone really experimented with different CCA to see whats required?
Personally right now I wouldn't spend the extra cash for a GEL or AGM battery. The lithium iron phosphate market is developing rapidly and will truly be the next thing in auto batteries.
