swing because don't think anyone could help my mind in an hour
however, swing is not a no brainer. when I was hitting fatties and slices decades ago, I wasn't thinking about much of anything and the swing coach would be easy choice. As I've learned better mechanics my mind and or the lie/footing that I have are now the biggest challenges to a quality strike.
maybe I'm the only one who rushes a chip but even on a shot requiring no power I often get sped up; seems more mental then stroke mechanic to me.
