Select X1 wave for Queens type Bump and Jump.
I have a 23 and 25 Demo X1 you can try anytime Lee. The 23 for over 20Ktns and 25 under. (I use them in the trusty Evo 92 2006 and these days always the 5.4 sail ). The 25 goes very well with 6.1 and the 23 I have used well over 30 knots. Being so light you could get away with the 23 only.
If you are heading pass drop in to the house to get them Lee.
