old....as far as the new grips check out Shrewd. They make "skinny" grips that you can order the type you want (high wrist, med., or low wrist). If you didn't modify your grip on the palm side you might want to do so. You want to make it skinnier, may be causing torque. Couple of other schools of thought...Draw length. In my experience, a too short draw will cause occasional lefts. Too long will cause occasional lefts and rights. You might want to try to adjust just a little to see if it helps. Different bows with different ata will require a different draw length to "feel" the same. I know my MQ1 needs to be hard to the wall when I draw, or it is inconsistant for me.
