This Titleist Scotty Cameron Phantom X 5 Putter was recently given as a gift to me. It was used indoors a few times on my basement putting green and never taken outside. It has premium 40 weights. As will all of these, the weights can be changed to your liking.
I have the same putter in my bag and find the 40g to give me excellent added stability. As I already had the same putter for my home, this makes the 3rd one for me and I don't need three!
