I voted no because sometimes all it takes is one swing tip/thought to make an improvement at a certain aspect of your game whether it comes from a touring pro or your next door neighbor. Conversely, all it takes is one swing tip/thought to do damage. The trick is finding the ones that work and discarding the ones that don't quickly. I feel like I'm pretty good at doing this, so I'll take any tip I can get and then either discard it immediately, try it and discard it immediately or try it and keep it until it stops helping. I tend to use a collection of swing thoughts and pick one appropriate for how I'm hitting the ball at that particular time. For example, if I'm pulling my drives badly, most of the time it's because I'm coming over the top, so I find that focusing on my swing plane helps. Other times my drives are straight because I'm maintaining the plane through muscle memory, but maybe I'm not starting my swing with my lower body, so that becomes my swing thought. I guess this is contrary to those of you who prefer a more rigid and structured set of thoughts; this is what works for me. If a helpful thought happens to come from a touring pro, I suppose there are less qualified sources.
