Yep right up to the point you slice your first drive into the woods. I'm guessing / hoping this is your form of sarcasm.
In case it's not, we can game plan all we want but in the end we have to play the ball where it lies and since even the pro's can't keep it in the fairway an entire round. A game plan that assumes you will only be on the fairway is likely a plan that won't be very effective.
You were given multiple answers, did you read them? A Scotty Cameron 009 is a collectors item, they are only made for tour players in very limited production runs. The 009 is based off the Newport head that most people could buy for $350, but there are still differences between the two heads and again the 009 is a collectors item.
Most Anser style putters look similar but just because they look similar doesn't mean they are the same. Putters are made with different types of steel, some are milled, others are cast, different tolerances are used. If you look closely, which is why many of us think you're trolling, you can see there are obvious differences in how the putter is constructed.
If you honestly do not get it then I do not know how you have made it through to your old age.-Some things are worth more and your putter looks like a piece of junk.
Stop pushing your value system on others.-If someone wants to spend a month paycheck on a putter good for them. If someone thinks your putter is not worth using as a fire poker good for them.
But count me among those who do not think there was anything honest about this thread-Cuz if it was honest I have to wonder how you got through life to your 60s.
Congrats on the weight loss!
The swing you had at 75lbs heavier likely compensated for your additional girth and reduced flexibility. Unless you were very flexible for an overweight person your current body is allowing you additional movement your old body didn't which could throw off your swing and or timing.
There are a few pro's who lost weight and struggled with their swing, some worked through it like Dufner while others gained the weight back.
You'll likely find with the additional flexibility and smaller waistline your swing speed will increase so you may not feel the benefits of graphite are necessary any longer.
Give it some time, it probably wouldn't hurt to take a lesson and have someone check your swing to make sure it's looking okay or create a My Swing thread here and post some video.
