Using the line on the ball to line up your putt...
I brought this up on another thread about using your putter to line up your putt, but didn't want to get any farther into hijacking that thread. I mentioned that I'd like to see them make that practice illegal, mostly to discourage club players from duplicating the increasingly popular tour move of putting the ball down, addressing it, adjusting the aim, addressing it, and continuing to do that until the player is satisfied it's all lined up and then eventually actually striking the putt. I had the unfortunate experience of playing with someone doing that, and it was not fun.
I don't know how many guys on tour are doing it now. I don' know if Furyk is still doing it, but I remember watching him go through that routine and thinking, "welcome to the 6 hour round"...the idea that this could filter down into club play is scary to me.
It seems to me that banning the practice would be in keeping with other rules designed to eliminate help lining up, like not having your caddy behind you while you aim, and not being allowed to lay clubs down next to your ball, etc. etc.
What do you think the ruling bodies are thinking, if anything, about the increasing use of this routine?
