You can leave the coastlocks on your flashers......and put a bead swivel on your hoochy leader and connect it to the coastlock on the flasher when needed.
But now you have a welded ring, a coastlock with a swivel that came with the flasher and now another swivel on the leader end of the hoochy.....
too much swivels and hardware.
Another choice:- which is what I actually do personally.:- I cut everything off the flasher at the back except the welded ring.
I tie the hoochy (or spoon) with a bead swivel at the end of the leader.
I buy these little clips from Pacific Net and Twine.......they are diamond shaped and about 3/4 of an inch long.
They are 200lb break strength.
They can be affixed to swivels or ring in seconds.
I leave one on the welded ring of every flasher.
When I'm on the chuck I simply take the pretied hoochy or spoon with the swivel and connect it to the clip.
No muss , no fuss, can be done in seconds.
Never had one fail.
Minimum of hardware....yet effective.
I only want one swivel between the hoochy and flasher.......no more.
others will argue that you get a better 'whip" action on the hoochy by tying direct to ring with no swivel.
But every time you want to change one and cut it off you mess up your leader length doing that. And it's time consuming retying hoochies.
One swivel on the line will not mess your action up much. But if you've got 4 inches of hardware,multiple swivels and whatnot....that's a different story.
No....offset -eye hooks are NOT o.k. to use on all lures.
Use these on hoochies and use an egg-loop snell knot. Because the snell knot will make the hook "hang" right in the hoochy. You can use a closed-eye Siwash inside a hoochy but make sure to put a bead swivel in front of that hook.
If you use a closed-eye Siwash inside a hoochy you will use ONE hook.
If you use offset-eye salmon hooks you will generally use TWO hooks inside the hoochy (with no swivel inside inside the hoochy). You use beads or "gumpuckies" for spacers with the offset hooks.
When you tie a snell-knot for a hoochy....and you put the hook inside the hoochy behind a larger bead...you will notice that when you pull on it, the hook willtend to kick out of one side of the hoochy. To get around this
ut a micro-bead in front of the offset eye before you put a bigger bead on. This will counteract the offset angle of the hook-eye and it will hang a lot straighter in the hoochy.
The micro-bead you use for this is really tiny....less than a sixteenth of an inch in diameter. You can get these in the better-stocked tackle shops.
On a regulat sizehoochy, generally you use TWO offset-eye salmon hooks (4/0 or 5/0), one behind the other, both snelled.
Some guys like the hooks "one up-one down" facing....I happen to like both facing down.
For spoons use an "open eye' type hook.....open eye Siwash or closed-eye Siwash. Open-eye if you are replacing a hook (you squeeze the eye shut with pliers when it is on the ring). Closed-eye if you are putting it on a split ring on a spoon.
Plugs usually use a "beaked' hook and it will be bigger. Partly because it has to be big enough so that when it flops around in the chuck it will not "hang up" saddled on the plug. These come in "open-eye" so that you can rig them yourself on the appropriate swivel or beadchain for the plug.
When I'm on the water I don't like to be messing around tying hoochies or spoons.....which is why I use the method I do. I like to maximize fishing time.
I don't want to tell a guy to butcher all his flasher hardware if he doesn't have a suitable alternative.
But that is what I would do ...and have done.
Open-eye Siwash hook:- used on spoons when you are replacing a hook to a welded ring. Also can use for hoochy but must have barrel swivel in front of it inside hoochy.
Closed -eye Siwash hook:- used on spoons when it has split ring instead of a welded ring. You just slide the hook -eye into the split ring until it's on.
Off-set eye "salmon hook".......use these for hoochies or when rigging bait. Don't use them on spoons. Always use a snell-knot for offset-eye salmon hooks.
Once you get the hang of how to tie an egg-loop snell knot it is easy. Can be done in under two minutes.
For barrel swivels.... use the plated steel ones, not the blackpainted brass ones.
Brass is not as strong as the steel ones.
