As a clarification: when I got into DG, I started with Aviar P&As. I practiced a lot, worked on my putting form and style... and remained uncomfortable and unhappy with my putting. So I tried the Judge, the Warden, and even the Wizard. The Wizard hit the cage a lot, and I did better with the Warden, so it won.
When I changed my putting style to more of a spin putt, I went to the beaded Marshal over the unbeaded Warden when the Marshal came out in Classic plastic. I also re-tried the Wizard, and had the same problem with it as before: I hit the cage a lot. The reason was because I was used to the slightly higher glide of the Judge, Warden, Deputy, and Marshal. I could practice with the Wizard forever and made it work, but the Marshal was a better fit for my putting style, and I've gone with it and been happy with it.
So that is the basis of what I posted: to make sure one knows what will fit one's putting style instead of trying to force the issue with a less-fitting putter. Practice does not make perfect; only permanent. Practice is great, but one has to practice with the right tool, or the practice is wasted.
TL;DR: Don't put the cart before the horse.
