I knew this was a ball I would be excited to drill as I had been looking for a shape similar to the original Physix and I have found it with the RST X1. Although not entirely the same the RST X1 provides a tad cleaner and stronger shape down lane compared to the Physix.
The RST X1 will be good for medium to higher volume as well as those harder lane surfaces that are conducive to Asymmetrical's.  The RST X1 provides plenty of punch in the the HP4 line.

Layout: 75 x 4.5 x 35 (pin up, over ring finger)

Love, Love, Love this ball!
If you can’t use a big ball like the UFO, but the medium stuff isn’t quite getting it done, say hello to the RST X-1! This ball is cleaner thru the fronts than the UFO but has way more backend. It is stronger than my Idols and the Rubicon, but very easy to throw. Whether you like to go up the 2nd arrow or get in deep and bounce it, this ball absolutely crushes the pins. The torque this core creates makes this ball hit exceptionally hard with a nice “Crunch” sound as it rips the pocket. It also finishes stronger on the backend than my Nuclear Cell, which makes sense, since this cover is Micro Trax (Nano based). If there is any oil carried down, this ball doesn’t care and continues to hook right thru it. Bowlers that feel they lost a little power because they can’t use a weight hole under the new USBC rules, need not worry anymore. All styles of bowlers will easily find a spot for this ball in their bag. It is not the most hooking ball out there, but it is one of the most useable balls out there for a large variety of bowling styles on medium to oily conditions.
