Used the big Manta79 + 46cm fin and 2013 7.9 Vapor today. A cloud with rain and wind hit Herkingen during the day and the speedstrip was almost perfect during maybe 10 minutes. I could do 2 nice runs, with a 66 km/hr max on display. Probably a set PR for me. How fast can you go with a 46 fin and a big board???
