Picked up a pack of Kinami worms today.  Couldn't tell any difference between the Kinami worms and senkos.  They are both made by Gary Yamamoto........anybody know the difference besides a different colored package?

Nothing different.

Same price per bait.  Less in a package.  Do a search lots of info on this topic.

Same company different name.  Kind of like a Ford and Mercury.  Same parts just one has a "Better Name" for sales, but look under the hood and it is the same thing.  From what I heard Gary runs the "Yamamoto" name and  Derek Yamamoto runs the Kinami line.

Please read the Senko FAQs, as this topic has been discussed in great detail.  Links to those threads can be found there.
