1) Yes it's worth buying
2) It has a nice slow meter, and has more power ratio's 15, 30, 60, 90, 150 and 300 ft scale. The only other putter that comes close in my opinion is the beginner one. Your not high enough level for the ghost yet, but if you were thinking of getting that one, you'd have to relearn the power ratio's over again as there completely different to the other putters, which is a shame as it hit's the ball beautifully. But I don't have the energy to get to grips with it. so for me the Daytona rocks above all others.
