I fish a fair amount of hoochies on the BC coast. I tie my leaders with 30-40 lb Maxima Ultragreen with two single 4/0 hooks, same egg loop knot as my cut plug mooching leaders. Spacing between hooks depends on how many beads or tubes used. You want the back hook hanging at the end of the hoochie. Captaindownriggins ties some nice hootchies and useful info, as does salmonuniversity.com - some good ideas can be used by refering to his design:

Salmon fishing around Victoria area has been slower than usual. I fish Port Renfrew and it is picking up nicely, consistent catches and good size. I hear further up Vancouver Island is doing well, e.g. Port Hardy, Tofino. Send me an email if you want more information.
