gedi83: High level ghost, L70 Versa or high level Max are all better than Rossa. Of course if you always used Rossa, it will take time to adapt (24 hrs of rental time are probably not enough for that), but once you do, it's clearly better. With these putters, unlike with Rossa, 10 footers are more consistent and (mostly straight) 20 footers are no longer at chance level... Also 5 footer misdings are usually in.
Right on gedi. I am noticing this in the very short time I have used it. I'm not a 6, 7 , 10 game "a day" player,,lol , waaay to busy with kids, friends and work for that. This is the reason I hesitated to upgrade, but at the same time I was tired of missing birdie putts by "inches", either left or right of the hole. Hey, if I can save 2, 3, maybe 4 strokes a game every now and again then it will have been worth the investment.
