Speaking of weedless wacky for Senko type baits, the Weedless Finesse Wide Gap Hook is not bad in the larger sizes like 3/0 and 4/0 but a better weedguard setup is an Octopus hook with a weedguard. Since no one makes them, but you can and very easily. Parts needed are a 4/0 Gammy Octopus Hook #02414, a piece of 1/8" electrical shrink tubing, and some stiff 20#-30# nylon mono or fluorocarbon line. Start with about 4" of fishing line, slip about 3/8" of the electrical shrink tubing on the hook shank, double the line and put it thru the hook eye and into the tubing. Adjust the length of the line loop to bend over and catch under the hook barb. Heat the shrink tubing slowly as not to over heat the line (I use a barbeque lighter) and clip off the excess line. It will look like this--it takes about 30 second to do one:
Rig the hook in the Senko perpendicular as it will have a better hookup ratio than parallel with an O ring. Use a short piece of 3/8" electrical shrink tubing where you insert the hook and the Senko will last longer.
