Not sure what Scott means given the bulk of the history shows non-putting competitions. Looks to me like a concerted effort to learn the game.
That L19 Spider isn't a very good putter but there are a lot of them out there. Missing the ding seems to work well with it. I used the Redwood for a long time and it does a decent job by missing. Not so sure about that Ghost, though. If it's anything like the L97 version it doesn't handle missing the ding as well as the other 2.
Whatever you decide on, give yourself a good number of rounds to learn it and then stick with it. You're not buying putts, you're buying better piece of equipment that you'll need to learn. GL
