I have the original REAX, and the REAX Pearl. I also have a Yeti Untamed. My favs so far are the original REAX and the Yeti Untamed. I am getting the V2 Pearl hoping for more angularity on the backend. I like that the Yeti Untamed is a symmetrical core. Really strong ball motion down-lane with a good clean look through the fronts, which is something I haven't seen much through the REAX line. The one thing I have noticed with all my REAX stuff is how even it is across the lane. Even in layouts designed to push the length further down-lane and make it corner harder, it still retains a very smooth shape. These have probably made the REAX line one of my most used on flatter patterns. And like I said, the Yeti Untamed has given me the angularity on the back of the pattern so I feel like I have a great complimenting arsenal now.
