IRL I swap putters too often. Toy shop intoxication, gear freak and trying to repeat those few (way too few, LOL) that seemed to really come together. Past a certain early point it's not the putter though any more than here, but all a laugh over a beer at the 19th ( including for the local pro shop with another sale too, LOL).
Here so much "feel" must come from only increments (putter pal / avatar moves), and so arguably it's even more important not to swap so often. Hitting 5' on a Nike L77 on the 10' scale is not the same as 5' on the 15' Versa scale.
IRL a roughly same weight / shape putter in your hands you can quickly feel if your 10" power draw distance is 10' with a new putter, and adjust around that "feel". Here all must be learned with each increment to get that feel.
Load a decent putter, stick to it and your game will return :).
