On my 5.2 I used regular nylon strapping and some hose to make nice cheap footstraps. You can bolt them straight through the hull, easy since the 5.2 has those lovely inspection plates. I single almost always and i find thse make life easier in big swell (its not uncommon for me to be out in 10' swell or bigger) As for the jib blocks, I did away with that system, I made my jib self-taking, I also moved the fore-stay clear out to the front of the boat, which allows me to use a 5.8 Jib, if I'm a little camakaze.
