Fastback 1, to be exact. I have a straight back and straight through style so I needed a face balanced putter. I loved the SC Red-X when it came out and was very close to getting it, but then I decided I wanted something newer..and the Fastback 1 fit the bill. They are truly works of art and just look so right.
I'm a member over at The Cameron Collector and they have a bunch of good folks that are selling Scotty Camerons left and right. I got mine from a fellow member over there, it's 34" and 350g..and it fits like a glove. Does it make me a better golfer? wel..does owning a Lamborghini make you a better driver..does owning a Rolex make you tell the time better?..you get my drift.
Anyway, I can say it does give you a sense of confidence knowing that you are putting with one of the the best putters available..if not..the best. If you've been looking here and there for a putter, pick up a Scotty..I guarantee you that you've reached your destination.
