I have the Tundra, which is basically the same riser but with different limb angle and longer, recurve limbs. I pretty quickly took the grip sideplates off my bow. I didn't care for the feel of the sideplates, especially the left one. On several bows I've owned, I tended to get a right tear like you are talking about. With the Tundra, and the sideplates removed, I am not having any problems getting it to tune. I've only had the bow for about 3 weeks, but I am really liking this bow, ALOT!

It may not help at all, but I would try removing the grip sideplates and see how it does. I am planning on putting some camo fleece on my riser grip area for this hunting season.
