I feel this is part of the noob trap. Really many things that can be seen in the throws of McBeth, KJ, Heimberg....don't really translate to the noob or rec player. Don't get me wrong, there are always a set of mechanics....SW is very good at providing information for use along this lines. But, professional, high level, disc golfers have different goals and play different courses.
I cannot tell you how many times I "discovered" more distance in a flex line. Only to learn something new that translated into more distance, but I then move back to a hyzer line to learn and use it. Lo and behold, back to the turnover flex....only to learn to stop rounding....
Each plateau seem like I had it ALL figured out. But, really I was very slowly teaching myself basic mechanics to build on. Building a foundation for years of safe play. The drills and videos, many post here, are designed to build that foundation. They do not translate in to the ability to throw a putter 500 ft. They are not designed to retro fit your noob form to mimic the Conrad run up, KJ putt.
