Putters are almost always a "What feels best to you?" thing in my opinion.
I putted with SS-4S wizards for about three years then switched to a beadless putter about 2 years ago. When I switched putters I stopped resting my index finger on the bead and now use more of a fan grip when putting. I seem to generate more power with this grip now.
Mint was going to be my suggestion too! It's a great distro for a lot of users. Easy to navigate and hard(ish) to break.
