I will try the vector fins. Very quick reply now indeed within a few hours.
For now i have lost my trust in deboichet. No reply and worse, when ordering a fin you have to wait what they send you. Some time ago i ordered an R19 S-- and a R13 S, but the fins are not soft at all. The are worthless to me. I don't know about slalom fins, should be less critical then formula fins i guess, but for that amount of money you may always expect a good fin (within certain tolerances) in my opinion.
