I just got fit for a putter this past weekend. I was fit on the SAM Puttlab machine but I think it's similar to the one you got fit on. The most important thing I came away with was the importance of loft. I've always had a slight forward press as a trigger and I've never been able to get rid of it. The camera showed that my effective loft at impact was +1 deg. almost all the time. The fitter said that would be fine on pure greens or astroturf ones, (I have a green in my backyard and I roll them great on it) , but on the poa annua I always putt on it wasn't enough. He gave me a putter with 6 degrees of loft and said don't change anything. Almost immediately I was rolling them really pure and I was starting the ball on my intended line. Sometimes when the greens were a little fuzzy the ball would jump off line, not anymore. My point is the $100 was well invested. As long as you don't have any crazy measurements, almost any putter can be adjusted to your specs by someone who knows what they are doing. Good luck!
