I had to do it last week when I got a good puff and ran a little too deep going to the finish line. I had the choice of either dropping the spin and reaching up to the finish line, or get out on the wire to cary the spin higher in the gust, which I did, and it was no big deal. It will allow you to sail higher with the spin up.

Usually I stay in on the tramp to fly a hull and run deep, but if you have become overstood and need to get back up high to the mark, do it!
