Today Halewijn and I tried the new Sonntag SL-X 37 and 39.

I ordered the medium and high wind version as I already own a low wind SL-R 39

Joerg already mentioned the X is slower than the R and I agree, but as the my X models are for high wind they are also fast but the control is better!

Display speed on my Gyro GPS was 61.08 km/h avg, in GPS Results the score was 61.09 km/h avg!

Overall a very nice session :)

Started with 4dgr and ended in 8dgr with some sun
