Today I had a great time, nice sun and I didn't focus on getting as fast as possible. It was great just testing and taking my time thinking about what would be intresting to test more.

I tried 3 fins.
The Sonntag GPS_2 26cm was fastest average.
The Caspar Speed 25cm did the 1th and 4th fastest run
The Sonntag SL-S 28cm was a bit to big

Joerg/Alex, the GPS_2 is working great!!! Can't wait to test the real topspeed :)

Cheers,

Erik
