Its not a bad option if your into racing and it looks too windy or have a light crew, you can still go out and stay in the competition. I've done this when I was a few kilos lighter on my first 16. I'm disappointed my new boat doesn't actually have the reefing points so I might get a sailmaker to put some in just in case. Another option is to get an old hobie 14 main to use when your fuzzy dice are blowing horizontal.
