Jody,
I hate to say this but on 80 % of the F16's I've seen thus far the spi sheeting angle is too horizontal. This will make it appear that alot of tension is on the spi sheet, when that much is not necessary.
If the spi sheeting angle is too horizontal then you are pulling really hard on the sheet to prevent the luff from curling up. Having to the correct sheeting angle requires alot less sheeting tension to get the same results.
I need to see pics with the spi flying to determine whether the sheeting is off or not. Maybe you can also tell whether the full of the spi is tight (instead of loosely curved) when sailing.
With respect to tiller extension and light wind upwind sailing. The solution is simple.
When sailing two-up then place your crew on the leeward hull and far forward, the skipper can now sit back a little further and have unobstructed steering. When singlehanding you don't want the main traveller perfectly centred anyway. For some reason the superwing rig doesn't like that. Travel down about 1 or 2 inches and the rig will be happy and you as well as now there not be anything obstructing your tiller extension.
