I'm debating Scotty vs the rest. I love the way the Newport line feels but also like the Ping Vault 2.0. They both feel firmer than the other putters I tried.
I have played Mallets for the past 15 years. Had a putter fitting with a SAM and all of the fun stuff and was told that blade would better suit my stroke. Switched and haven't looked back Scotty Studio Select Squareback 1.5. Never thought putter fitting mattered. Had a friend get fit was put into a spider. I don't change clubs much but this was an eye opener.
