If you are around the bottom in that 25-30' then a Carolina Rigged Keitech-type bait or top hook line through like an Osprey or Optimum works best for me. 3/4-1oz on 20lb Fuoro and a long mono leader. That's the easiest and most effective way of fishing them at depth. I've tried Hudd rof 16, and fast sink Spros, they are really hard to keep deep.
Suspended at those depths, swimbait on a spin-head type head.
