Red Gill Teaser Rig - Input Wanted

[Joe]

So....
I got these Red Gills and I want to make them into teaser rigs. (The 4.5" inch model)
I'm looking for suggestions on what would make a super-high quality surfcasting teaser rig.

I have Spro Power swivels - I'll be using them for the top swivel.

Should I use a duo-lock snap for the plug end, or should I use a Spro Snap/Swivel?
I'm leaning more towards the Spro.
The Spro 100# Snap Swivel is very small, smaller than most duo-locks. (I have Roscoe/Sampo stuff on hand too.)

Should I use Seguar Flouro, or something else for the leader material? It has to be fairly heavy.

What should I go with for the Red Gill hook? I'd like to use high quality hook like a VMC - but I'm not sure which model would work the best.
I measured it, and it appears that 4.5" Red Gill accepts a hook with a 1 3/4" - 2" shank.
I'd be ok with a hook made by another manufacturer, so long as it is well regarded. I'll need a model number.

I'll give a nice plug to the person(s) who provide the best help...
Thank You!
