I use a combination of two different Aviar's (one very light 150, and the other a 172), and one fairly light 165 Element X, depending on conditions. I usually putt with my heavier Aviar, but if theirs no wind, I have excellent luck with either of the lighter putters.
I use Gateway Warlocks - usually Super Soft. I used to putt with the Wizard, and I still use it for approach shots, but the Warlock gives a nice straight shot with a touch of fade if I need it. The biggest difference is that I attack the basket on the left side instead of all the righties attacking on the right side.
