Congrats and welcome to the soft plastic side of fishing!
That's primary for me, wacky, Ned, drop, and so on. All do
produce fish, in fact, the Ned has not allowed me to be
skunked once since I started using it - even when my go-to
techniques failed!
Anyhow, 4" senko-style have been my most successful size,
despite buddies killing it in the same water with 5" versions.
I just didn't have the same luck. That said, I did get my PB
on a 5" senko...but that's another story.
