Unless you're one-putting everything it's worth looking around I think. I had a Rosa for over 10 years then I talked my wife into getting me a Piretti for my birthday and it's been better in every way. My first putt in a game was 15 ft sidehill and down and it dropped dead center and I was draining putts all day. Gave the Rosa away after that.
It's worth mentioning that a few weeks after getting it I used it to win a Scotty at a charity tournament so it would have paid for itself if I'd consider selling the Scotty. It does look really good under the bed though so I guess I'll keep them both. Along with the Craz-e, Scotty Studio Select Fastback and Newport, Odyssey White Hot Pro. Anyway, you get the idea.
