As we're a little bit house bound today (our choice) from all the fire smoke, I did a little indoor putting. The smoke has been around, on and off, for a couple of weeks but not too bad... until last evening. It really started to smell and the higher humidity and still air has allowed it to settle in the valley...yuck. We're close to the arrow.
Because our carpet is a very low pile and actually rolls pretty darn true, I decided to run some tests. A rubber lid opener/gripper serves as the hole.
I applied some alignment marks for the heel and toe strikes and we're using a brand new sleeve of Kirkland's .
I'm trying to assess both the dispersion and length trends between the B61 and the ER5v. I'm rolling 3 balls at a time, first from the center, then heel, then toe and repeating this to establish some trends. The spray powder shows up very well on the B61 face but not so much on the ER5v. Each of the photos had one set of (3) strikes from the intended face position.
To be honest, I'm not seeing any specific trends between these putters other than, in aggregate, I'm short right more than any other miss. Toe hits tend to be shorter on both putters and I could make a weak case that ER5v heel and toe hits stay on line better than the B61. I'm able to fairly consistently strike the intended face position but putting force and face path is probably just too varied to ascertain whatever benefit the "Sweet Face" technology affords.
Once the smoke clears out, I plan to repeat this at a practice green and see if that makes a difference. But at least I've got the align marks done and feel I can accurately hit test area on the face. I want so much to really test the anecdotal claims that off center strikes tend to stay straighter and roll out to the same distance as center strikes... but a putting robot is probably the only way to test this .
I did a quick search to see if any independent labs have attempted this (repeat the Guerin Rife test) and have not found any. If anyone knows of any such test, please share with us .
