I see that Titleist has come out with new alignment aids on the ProV series of golf balls. I personally have no success with the added alignment stripes. I tried it and really gave it a serious effort, but my eyes got so focussed on the alignment on the ball that my putting simply got worse. There are truly two schools of thought on putting. Some really like the alignment arrows while others prefer to focus on something else. Personally I am one who has learned to focus on a spot about six inches from the ball which allows my putter head flow towards it. Which group are you in ??? Alignment lines or clean ball ?
