Every time I get to a narrow tunnel shot, whether I X-step or 3 step, no matter what distance or fairway driver I use, I end up shanking the disc or slightly throwing the disc right. I do not have a trouble with throwing it flat, or throwing it level, but just throwing it right. I throw my distance and fairway drivers around 300' and most of the time, the discs that i throw right are gripped with a power grip. I feel like its an issue with my hand grip release and my stepping approach, but does anyone have any basic advice on how to throw dead straight, and not release it right (at least with the arm or grip release)?
