DrSlick:curious on what putters some of the big guys would recommend
Leave that 1 for them. For my 2 cents a quick look through the leader board reveals a few work very well in the right hands.
DrSlick: for a gent that aims and then off dings according to feel.
For me the new HL Mallet competes with the L92 Ghost (usually looked at as ding style putter), just with a faster meter and 600 credits extra. If that's the case definitely not for you IMO! The new putter I doubt will be for me either, but people wanted the extra choice so can't complain at that.
DrSlick: away from the inexpensive Rossa that would give me 2-3 strokes per 18?
I am just in to L95 and happy with my L70 Versa for now. To your question though I don't think any putter does that. There are threads where top players have posted videos how they do it. I think watching those and practice will be worth more than any putter upgrade in itself.
