I have the honor of supporting my dear golf colleague Heinz Schönmann, a member of Handigolf Suisse.

The Swiss team at a tournament abroad.

I try to build and optimize golf clubs based on his feedback, so he can achieve the best results while playing one-handed. By the way, his drives land just shy of the 200-meter mark.
This is a real challenge for me because I lack comparison values, so I have to figure out through conversation with him which parameters need to be adjusted.
