Slow,
The best way to fsih a senko is dead sticking but..making long casts is not a good idea because you will miss alot of fish I reccomend using a MH to H rod and making short percise casts to get a good strong hook set. I usally use a 5/0 owner stright hook on the 5" when flipping and pitching around cover and a 2/0 owner mosquito hook for wacky rigging which is great in open water. Senkos are very effective on suspended bass and spawning bass just keep postive head when fishing them and you will catch lots of fish on them! Just let them hit the bottom bump them a few times then pull it back upto the surface and reapete. I suggest you get BLACK, Watermelon and Bubblegum these are my 3 favorite colors they can cover most any situation you will encounter I would also suggest the 5" they have alot more action.
