Hey Gadget, the best thing to do if you are riding a Fuel unhooked is to either add a 5th line to it, or make your self a good suicide leash and pick a less crowded place to ride and ride downwind of everyone else.
The other alternative is to attach to a single flying line, but this will result in tangles almost everytime you drop the bar or miss a pass.
Go suicide equipped with a good quality safety release at the harness end of the leash, or go 5th line.
Good winds,
