I mostly rig my boat solo as well and I used the method described by Jalani. Matt was the one that told me to use the spin halyard attached to the bridle. I WAS attaching it to where I'd put the fore stay, but that was a pain as I'd have to work around it while attaching the fore stay to the bridle once the mast was up and in place by the spin.

Matt later told me that someone posted a trick on here to attach the spin halyard to the bridle tang (as Jalani mentioned) in order to avoid this. I was worried that this would rip out the tang but then he made a great point that it only has a couple of pounds of load as it doesn't take much to hold it forward. Just make sure the stern is in the wind and it becomes very easy. The apex of the bridles are left free to attach the fore stay. Life becomes easy again :-)
