I'd say the Edel, putter fitting is excellent, to a point, it fits you for aim and speed, but not for stroke.
So your Edelman will point where you want it to, thanks the the combinations of neck, headshape, sightlines. It's be effective at distance control thanks to the weight, placement etc. It'll fit you for length and lie, which again aid aim.
The flip side is the torque balance suits only a narrow range of stroke. So if your Edel fitter can fit for the entire Edel range that covers all the toe hang option, then it's a no brainer.
I think the holy grail, would be to go and get Edelman, fitted, then ask a good club builder to make you an evnroll to those specs?
