I don’t see any downside to soft spikes because there are so many variations. I’m surprised the players on tour haven’t done something about players that use them.. you want to putt over their spikes marks when metal are not necessary.
The LD guys don’t wear metal so any PGA tour player that says he needs them for grip ... should “get a grip”
I have a 7W and it is one of the club that I use most often. I mainly use it for my 150-160yd approach (on raised greens at my club). I have very high launch angles so the balls don’t roll much once it gets on the green. Sometimes I use it to bump out of the rough when there are trees nearby. I love my 7W so much that I have a backup in case this one breaks!
