I'd stay away from the lessons, unless there's a TGM AI there. Getting lessons from somebody who isn't on the same wavelength instruction wise presents problems IMO. So I would just use the camera, and the net. If there is a TGM AI there, then I would work with the AI.
I would suggest:
- The Taly
- The Speed Chain
- Some type of attachable laser for your putterface to check putter face alignment.
If GolfTec has a launch monitor, then I would probably want to try out some different drivers and get the launch and spin conditions optimized.
