As others have said, hang in there and trim down your tackle. Take with you only a couple of presentations and that’s it. Learn them fully!
As for Senkos, I fish a lake where I couldn’t buy a bite with Senkos until one day I bought a different color, then it changed dramatically. I was never a believer in color as I have a trout spin fishing background, color was always for the angler so I could see the spinner depending on water color. I’ve obviously since changed that opinion so get fancy with some color. Orange / Black (I forget the real name) has never failed me, regardless of water color.
About those Senkos. Next time out, try wacky rig on a standard J hook without any weight. Cast it into tight areas along the bank and brush and then watch that slack line. Yep, you’re going to get snags but your production will increase and your confidence will sky rocket.
I speak from experience of being exactly where you are at, I’m just a year ahead of you now. It will come together for you.
