I have a magical black box that sits in between my shoulders and calculates all of that crap for me....
No really, try not to 'over calculate' some things, golf is as much about feel as it is the physics. The only way to really know how wind and spin are going to affect your shot is to try it.... if it doesn't work, try it again, if it does work, remember what worked, but don't get all bogged down with notes and numbers you'll just end up confusing yourself.
That's what works for me anyways...
And as always.... Just Have Fun!
