Ya I weighed it and its right at 173g. It is the first (and only so far) soft neutron I've got. It just seemed to drop quicker than my other Anodes and Ions in similar and even lighter weights. Not at all saying that is bad just took some getting use to. I have a soft proton Ion at that weight and didn't notice much of a difference with that one. To me even though the plastic is more flexible it felt more dense, if that makes any sense.(im mike too ) Ever weigh those putters? its very possible that soft N ion isn't 173g :thmbup: but yes I like a lighter 165g proton to pair with the 177g on longer putts or upshots needing more touch. The flights are no different though just how the discs respond to lower power.
