hmm, I'm highly inexperienced (approaching my 100th jump, yeah, getting the beers soon...) hence forgive me for the stupid question. My intuitive response to the initial post was, use the knife to cut the stuck toggle, leave the other one and land with the back risers. Surprisingly this option never came up in this discussion. I suppose there's a good reason for not doing so, and I'll be more than happy to know it :)
