I may be wrong but I am assuming you are tossing the senkos weightless. If so, keep the senko and rig it on a 1/8 ounce Shakey head of your choice. That will catch some good numbers and size. That’ll get you familiar with bottom bumping baits for sure then you can branch out to better feel what a t-rig, jig or Carolina rig is doing. You can get weighted wacky heads to rig a senko wacky style. Ned Rig heads and cut down a senko or use one of your old tore up ones, nail weights to learn the neko rig. That senko can do a blue million things and all methods will trick bass. Most important is to give yourself time with new techniques. It is all about time on the water. It’ll come.
