Wow a lefty that moves his feet just kidding, for me being a tilt challenged bowler moving left is he11 for me. I have good revs about 10 degrees of tilt and higher ball speed, so i labor and labor at getting good ball reaction when moving inside. I usually have to use to strong of a ball to get it too corner but then the pop is gone so i tap all night. I find that more up the back for me helps tight inside lines because my normal release is around 60 degrees but i can vary it to almost 0 degrees when i try too. The tilt factor is what kills me when the heads fry and i need to move way inside, i go from thunder power to looking like a fluffer with no power.
