The Emerald Vibe is a little stronger ball than you might guess. The cover on it I believe is the same cover that was used on the Raw Toxic. If the lanes are drying out, the cover is going to grab, and probably give that sharp left you're looking to avoid. It will give you decent length, but it is a pretty strong ball especially if you give it some extra friction to work with. Not sure really what to recommend, as a Razyr may not be enough ball for what you want. One of the other, less aggressive Vibes may have been a good choice, but not sure if you can find one. Good luck to you.
