If fishing horizontal, I like to use a belly weighted hook, actually like the VMC drop dead hook for bigger flukes 6" over and also the owner twist locks and sometimes will use an underspin as well.
On a spinning reel, I would rig up a light split shot or slip shot rig for your son, light C-Rig is a great way to fish a fluke if he prefers to cast far and cover water. If weeds are not to bad, I love rigging flukes open hook with hook on bottom exposed and it keeps the head down so it dives better. Also takes away the challenge of feeling hooksets. Nose hooking is great as well if you can.
I also like to flip and pitch flukes and swimbaits instead of creature baits at times and when it works, it often works really well.
I prefer a fluke or sluggo over any other soft bait for Carolina rigging. I cast it a mile and if you simply reel slowly, it darts all over and you can get that lift and drop action....Split shot rigs on smaller flukes. If I feel structure or bottom change, I will dead stick it and slow down.
yes...I love a weighted fluke. Also love a double fluke rig, on top or bottom.
I probably fish a fluke more than any other soft bait and although it's not considered a "big" fish bait, I feel a 7" fluke will do just as well as a big swimming worm or senko.
I throw the Z-Man flukes for the 7" size and slug-go's for all sizes from 4"-10", lunker city, Bass Assassin, Hogy etc.
The Strike King Caffiene shad is my go to in 5" size and second would be a zoom fluke or Houdini Shad from Yum. Also love to fish the downsized 2.5" lunker city flukes.
