I finally got my hands on a dozen last week. Played a round with them yesterday and liked them alot. They seem to have less spin off of the driver then the HX Tour and Pro V1, I also hit my two longest drives of the year yesterday. I liked the spin and performance around the green, but perferred the feel of the Pro V1 more. I can over look the feel for now and say these are more new ball unless the HX 56 beats them out.
