I fish weightless flukes on a 6-7 foot medium heavy rod and size 4000 spinning reel. Seems to work well for me for both freshwater and inshore fluke fishing.

For what it is worth, I fish Zoom super flukes on a 7'2" medium Carbonite spinning rod with a Daiwa 2500 Capricorn spooled with 8lb BPS mono Excel, a 5/0 EWG Gammie (for a little keel effect)and a tiny swivel 18" above the hook to prevent line twist.  Always worked great for me.

you can tell winter is close, when these old threads get revisited.

Since it is reopened, I will give my opinion on the ideal weightless fluke setup.

I have fished soft jerkbaits since the sluggo first came out, nearly 30 years ago. 

After trying nearly every combination available, I have settled on a fairly simple and economical rig.

I use a Dobyns fury 733c  7ft. 3in. Medium heavy fast action rod. (I have noticed Dobyns rate their rods a little heavier than other brands. this rod feels closer to a medium action to me.)

With a 6.3 to 1 Diawa Tatula CT reel.

I fill it with 12lb High seas Grand slam Flourocarbon coated copoly line.

The rod cost $109.00 on amazon.

the reel was $99.00 on ebay.

This setup will cast a weightless Fluke or Senko a mile. Yet hook sets are still solid, when using heavier hooks.

I throw flukes on a Carbon light 7ft 6 medium fast action spinning rod with a carbon light reel.I use 10 lb flouro and a swivel most of the time.I can make longer casts and pick up more line with the longer rod.Even started using this set up for light t-rigged plastics.

I have a dedicated setup for weightless lures. It's a St. Croix Legend Tournament Bass "Teaser" rod with a Abu MGX. The thing can cast even the lightest weightless lures a mile, it's super sensitive. If you want to shell out the money for it, then I think you'd be extremely pleased with it, for what you are trying to accomplish.
