I should be around for the boat show, that is just a couple weeks before I leave, so I would hope to have my sail sold by then. But if not.
There are a couple ways to rig an asymmetric. I think the easiest is that you attach a block to your bow roller, as far forward as you can. If you have a bail on your bow roller, that is a good place. If you don't have a bail, then you can attach a block to a short (3 feet) line. That line runs under the bow roller and to a cleat. Then you run your tack line through that block back to the cockpit. This lets you trim the tack of the sail. You will want the luff tight when you launch, but once the sail fills you will ease the tack line so the foot of the sail flies horizontal.
There is also a device called the ATN Tacker. It slips around the furled headsail. It is set at a height to keep the foot level, but holds the tack of the sail solid, instead of flying free on what would probably be 6 feet of tack line.
The other thing to be aware of (this is probably the same as a J105) is how the sheets are run. You can setup for either and inside or outside jibe. The working sheet goes straight to the block at the aft of the boat (as far aft as you can place it) The lazy sheet then goes either outside or inside of the tack line. Hard to explain, but an outside jibe, the sail will flip completely in front of the boat. An inside jibe, the sail will be pulled through the slot between the forestay and the luff of the sail. The inside jibe takes a bit of practice, but once you get it, works better and is less prone to turning the sail into a giant flag in front of the boat that is difficult to recover.
The only video I have is when I was testing flying a symmetric without a pole, as an asymmetric.
