One thing about pre-round practice vs play: I've NEVER gotten a lie on the course as good as the ones I give myself on the range. On the range, I've always got the ball on a slight little perch. On the course, they are always nestled down tiny bit. For a decent player, this changes your whole "feeling" for angle of attack and shaft lean.
I've understood this basic self-inflicted phenomenon for 20 years. Have I quit trying to perch my ball slightly on the range....of course not.
yep. Theres a lot going on there too. Hitting the ball well is fun, practicing can be a drag...
