I really enjoy the freedom that the S70 and club sensors give me, in that I don't have to switch brain hemispheres between feeling my game and counting strokes.
I don't golf like an Ernie Ells or Fred Couples (sorry showing my age :D). In my experience, the real-world average golfers (ie. those who purchase the S70 and sensors) use mulligans and breakfast balls. Unfortunately, doing so messes with the automatic scorecard.
It would be great if the program let you tap to acknowledge those shots and track them. It is an important part of my scorecard stats and one of the best indicators of my progress.
