Karl, with your system, have you ever accidently -tripped- the halyard [and tack line] loose with your feet, during a gybe?
Disclaimer- I haven't sailed it singlehanded yet. (except a 1/2 mile up the beach, doesn't count, I know)
BUT, I may be stick boy, but I'm not exactly short, and Dan's no small fry either, so with both of swinging our limbs about we didn't have any issues. Like I said, the halyard goes through a strap on the front beam that keeps it pretty tight to the tramp, and its really only exposed maybe ~18" behind the front beam before it dives back under the tramp, so there isn't much to get caught on.
