I don't believe this ball will be much different then the 1st,
RG's are the same, with the diff on 1st one .050 and new .051.
The original had a 1000 Scotch Brite White Pad Finish and the new 1000 Abralon Polished. The cover is a little different as the original had Endurance X-Treme ( Particle  Pearl) and the new Flex Molecular, which might cause to hook up a little sooner.
Loved the original, looking forward to this release.
Try a Lane Masters, you wouldn't be disappointed.

 All depends on the Flex Molecular cover. Being rated for Medium Oil I would think it is a PP and yes I would think it would be close to the same as the original. Web site said a step up so I would assume a little stronger cover but how strong or what type is in question. I can say a ball with this core with a particle cover (Yeah Baby )is very strong and handles oil well. It would be interesting to see how the XDP compares to my YB.

Sweet, do let us know how they roll!
