I know Beavercreek is shut. Did you try calling WGC? Nothing on their web site says they are closed.
Was actually thinking about giving WGC a shot. It's been ages since I was last out there and my mom lives on that end of town.
For me it was finally understanding the 5 Simple Keys, then using video and good instruction, develop feels that matched good mechanics.
Video is a huge component to that for me. What I think I feel and reality are often different. So video helps me dial this in. I also used mirrors a lot.
Feels are very individual. Good mechanics to match are key.
