Scotty Cameron and Aserta both make good putters. I do not own either one of these putters, but I've putted a few balls with each. What I find amusing is all of the hype about these putters. I've got three putters that I rotate depending on the mood I'm in. I have a Ping Anser 2, an old TPM 13 and an even older Tommy Armour putter. And believe it or not No Three Putts is a pretty good putter even with these "classics". I am yet to embrace the modern putting technology.
It is hard for me to believe that a putter can make a golfer better at putting. Aserta is not shy about advertising that you'll save 6 strokes a round by using their putter. If this were true there would be such a buzz about their putters it would be as popular as the Tiger Woods scandal.
As for the Scotty Cameron putter $299 seems expensive for a putter, but I guess if Taylor Made R7 Drivers can go for up to $799 then why not pay $299 for a club that is used a lot more times per round. The one thing that annoys me about Scotty Cameron putters is the putter covers. I have never been a fan of putter or iron covers. Just seems a little anal retentive to me.
Aserta's big claim is that their putters use IVM, Inverted Mass Technology. What this means is their putter puts the weight of the club on the top of the putter head which creates top spin on the ball and eliminates skidding, sidespin and bouncing. Makes sense? I guess.
Scotty Cameron putters market two things. The materials, aluminum and stainless steel, they are made of and their sleek design which will "instill confidence". When over the ball you'll be lined up to find the true sweetspot. This also sounds good.
But why am I still not convinced Aserta or Scotty Cameron will make you a better putter? Because to me putting is about reading a green and having good speed control. Being able to do both of these things is what makes a good putter. Don't buy a Scotty Cameron or Aserta putter and think you will become a better putter. They might have a good feel when striking the ball, but it will take more than a putter to make you better.
