You can use the SLC 1250 to wing. It is actually really fun and works well. Will need some more wind and as mentioned it is better to start with a much bigger wing. The main issue is that the SLC was not designed to deal with the load of winging. That is why they came out with a wing specific line of foils.
Speaking of flipping wings... do that enough in the same direction enough times and my leash gets twisted. Is anyone doing a ratchet style leash (f-one) but with a swivel connector (o-zone)?
