Unfortunately your slide stop pin is rather high, and you're stuck with having to remove the pin to reef cleanly. This makes shaking the reef out a bit more of an exercise. btw - put a keeper string on the pin for that inevitable time that it slips out of your hand... it'll be sure to bounce overboard.
Also - highly recommend you remove the lines from the diamond patches.. you won't need them. The tack and clew lines will handle the loads just fine. If the reefed fold hanging down is a serious problem then just use them to lightly gather the extra sail. NEVER tie them tight to the boom!
