This is the best advice right here. From 10M and in virtually every putter flies EXACTLY the same, there are a few really overstable exceptions, like the zone and rhyno, but inside the circle the difference really is negligible.
Go to the store and feel all the putters there find, a putter that just feels great in your hand.
