I am considering a 90 litre mini dart for parawing.
anyone use one? I am currently using a North midi 96 litre and find it good but would like get something a bit lighter.
other suggestions welcome.

Im ~85kg on a 72 liter, Frank mini dart, 6' x 20" (same shape, modified dims and construction - lighter). Even at the low volume I'd echo the prior poster's feedback that its a relatively easy board. My theory is that the flatter, wider tail adds quite a bit of stability. I also find that it builds speed and the rocker releases it very well for its lower volume. The rails are quite forgiving on touchdowns.

The one thing that I have struggled with a little bit is that I find it pretty sensitive to foot placement on takeoff, and if I get it wrong it will pearl. Thats definitely a function of the volume/weight ratio that I'm on. For a lower volume board I might distribute a little more volume into the nose, but for neutral to positive, I bet its spot on.

Overall a board that I've been very happy with. I have several boards, but in the past year I've used this board 90% of the time. Mostly parawing, but also some winging where its also a great board.
