I have the R50, CT10, and S70.
Would love the ability to:
1) grab a club and have the R50 know what club since I use the CT10's. Sure this would be difficult but would be convenient.
2) If possible, have the data collected from the practice sessions be used by the Virtual Caddy software on the watch.
Great to practice at home and have the data used when on a course.
If it does that already....then great.
If not, just a suggestion.
