I used the Viper 44 up at the Nats on the first slalom day.
I had both the Sting2 44 and the Viper 44 with me but decided to go the Viper as the wind was pretty solid with the 7.8 and IS117.
It was mostly down wind slalom, the Viper was brilliant heaps of control where the Sting might have got a tad big.
It was only my second run on the Viper but it feels some where between the Venom and the Sting2.
Sting2 has more lift still which is what i used the 2nd slalom day as the wind was much lighter.
Still would like to do some more sailing with the Vipers but there been no wind here
