Jeff,

We too have noticed the weight sensitivity. Me transitioning from the N20 it's definitely more pronounced. We had the opportunity a few weeks back during training to play with this downwind while I was on the wire. I was moving for and aft and working on finding the sweet spot. Move too far back too quickly and you are really going slow.

Similarly, having the crew slide in and out while wired up in moderate conditions downwind with big puffs makes a HUGE difference in average speed. We still loose ground downwind but it's time on the water, and we're comparing ourselves to some of the best.
