I have found that the 4" Ocho worm works a lot better.

I think the 5 inch is the best all around length. The 4 and 6 inchers have produced better for me depending on the situation, however 80 % of the time, I stick with the 5 inch.

I use the 5" for LM, but just last year started targeting SM on the 4" using spinning gear. That tactic netted me my best SM ever at 3lb6oz on a 4" blue/black Senko.

4 inch is my favorite, the 5 is a close second

4" for me. I've caught tons of 6 plus lbers on down with

them. 5" was my PB, though, but I just don't have as 

much success with 5's. I've got a 6" that I rarely use.

Y'all ever wacky rig on a double frog hook?

I primarily use the 6", I find that the smaller fish 12" usually don't bite it.  I also see a majority of people using the 4" and 5" so I think a little bigger profile helps set it apart from other baits they have seen.

I used to throw the 5" senko but switched to the 4" after my wife kicked my behind with a 4" senko several times last year.  Not exactly a scientific study I know but the switch to 4" has not hurt my catch rate and I have confidence they work. I personally think the 4" works a little better when the bite is tough.
