After trying a few different options, I currently use the Crown for putting and it seems a tad underrated. It's reasonably shallow and on longer putters tends to be quite straight before fading at the end. I prefer this to the Shield which is really too deep for someone with smaller hands, and the Swan (2), presumably because I appreciate the bead although the putters otherwise have a similar feel. The BT Medium is a good putting plastic. The level of grip is sufficient and the disc is neither floppy or ultra stiff.
