Here's what Innova has to say about the Bullfrog:

Players want a putter that feels comfortable in the hand and delivers a consistent stroke. In jumps the XT Bullfrog with its natural, easy-to-release grip in a profile designed for aggressive putting styles. The chain-grabbing XT plastic enhances the feel and has the durability players expect in a go-to putter. Attack the chains with confidence knowing the Bullfrog’s minimal glide and wind-fighting ability keep it on target.
