Dear Ryan,
I'd love to help!
It seems you have a mix of mental and technical difficulty to sort out. First, stop having negative feelings about your skill on the course. You're obvioucly very talented with the putter, so you have to be more dominating on the greens. Get pissed at yourself first for your current lack of meanness on the greens and then get mean on the greens. That is, know you can do the same on the course as you do in practice, treat the course green just like a practice green, and don't really care if you miss or sink. Just do what you know needs doing, take your successful one-putt or just accept the two-putt and be patient. DOMINATE the course! and, paradoxically, let the green be your friend.
Second, if you are both pushing and pulling, it seems you are probably guiding your putts with hand action in the stroke. I would suggest that a shoulder stroke with dead hands is a lot better, with a lot fewer pushes and pulls. The trick is moving only the lead shoulder socket straight at the balls of your lead foot, down about 2-3 inches and then back up to level and then up vertically another 2-3 inches in the finish. This is a no-hands straight stroke that sends the ball away straight out of your setup consistently, so if your aiming of the face is good, your stroke will run pretty true.
There's obviously a lot more to it, and I'm more than willing to help get you on an ever-upward track, so try this for starters and get back to me.
Cheers!
