df,
We tie and use a LOT of deceivers in the salt. They get concocted from about 1.2" to about 12" in length and mostly white/white with plenty flash and silver. The size used is mostly dictated by what your target species is eating at the time with about 2" to 4" being quite common.
If'n they don't seem productive, it may be useful to have some shrimpy, some crabbie, and some squiddie type bugs to toss too.
This site has got a lot of'em to choose from with tying instructions too.
