I used to use an Odyssey White Hot two ball mallet, and recently changed to a Ping Redwood Anser.
The White Hot gave me a lot more confidence lining up puts when I was first starting to take up golf. I switched to the Redwood about three weeks ago, and what a differnce.
My distance judgement just seems to have improved no end, so that now I am getting balls around 2ft from the hole with shots 20ft and out most of the time. I can't see me switching back to the Odyssey anytime soon, unless things start to go drastically wrong.
