Roto Grip's Idol Synergy is exactly what it sounds like - a synergy of the Idol and the Idol Pearl, but with some fresh applications involved! The eTrax cover returns, this time in a blue-and-magenta hybrid formula and with a polished surface, alongside the usual Ikon core (low RG, high differential, symmetrical, rolly) from the rest of the Idol series. Rather than purely splitting the difference between the Idol and Idol Pearl, this one feels closer to an Idol Pearl in length but with a smoother AND more continuous/arc type response to friction. This leads to the Synergy actually looking very very good in situations where there's more friction on the lane, as Kyle Troup recently showed by using this ball to win the 2021 PBA Players Championship! The range of use is pretty impressive, and if you want a do-it-all ball for decent length and control this should definitely be on your list.
