Round 1 with the Sub70 was excellent. Especially considering this is a 395g head and I usually use 340g-350g. One 3-putt where I hit the 4 footer on line but missed the read by 2 inches. Otherwise made a couple of 15-20 footers, and was pretty solid all around.
I am going to have to practice the 3-5 foot range with the heavy head. I made them today, but felt very shaky moving that much weight just a little bit.
Very muted sound. I even had a couple of the 15-20 footers where one of my playing partners said she couldn't even hear it when I hit it.
