Hi guys,
Mine is the one in that photo with the orange jib. The three retrieval patches seems to work really well though I haven't used one with two. Seems to work really well for mid-pole snuffers as the 'snuffed' length is fairly short. We have our spinnakers set up with a halyard line and a tack line separate and when we're retrieving we let the halyard off first then pull the retrieval until it has bunched at the snuffer opening then let the tack line off. The only problem I've found with the three patches is if we don't get the tack line off in time then the whole thing grinds to a halt with a lot of stress on the bottom patch. But it does stop the whole thing from getting off the boat.
I use a knot in the halyard about 30cm (12 inches) below the top patch which seems to work ok. The bottom two patches go through together and then the top patch comes through just after to make not so much of a bunch.
