I like owners cutting point size 4 and 2 w/ straight eye for "old school" style rigging. For old school stinger hook you thread the leader through hook eye then down the shank through a small mono loop tied on the butt of the fly, hook gets attacked directly to leader behind the fly and attached by a small piece of junction tubing. You should use a straight eye trailing hook for this style so the leader applies pressure straight down the shank of the trailing hook.
For stinger hooks attached to flies I use Daiichi intruder hooks size 4 & 2 with up-eye, I use both senyo's intruder wire & 30lb FireLine for my trailing loop, that loop must be snelled over your hook to apply linear pressure against the stinger hook's shank while your fighting a fish. Also make sure your loop is long enough so you can change hooks after wire or FireLine is attached, for size 4 hooks your loop needs to be 1&15/16 inch long to allow hook changes, I can't remember the measurement for size 2 hooks. But it's slightly longer obviously.
Anyway, hope this helps.....good luck.
