Alright. Honestly, nothing, NOTHING can beat an original GY senko. Yes they are expensive and delicate, but it is the best stickbait out on the market. It is super soft which creates incredible, unmatched action. Although it doesn't come with scent, that's alright, I don't think it matters that much (I believe action will outweigh the scent). Plus you can put some on. Also, GYCB has the best colors and widest selection. GYCB also comes in sizes 3"-7", something fairly unique. This is my order of senko use (not counting Esquired's and Jim's senkos):
1) GYCB senko (Green Pumpkin, Blue pearl/hologram)
2) Yum Dinger (Bumblebee Swirl)
3) Tiki Stick Wave Worm (Sweet Potato Pie)
I primarily use the 4" size, but it is all preference. Remember, the Kinami Flash Worm is identical to the GYCB but less count per bag. Here are some pro's and con's of the GYCB over the Yum Dinger/Tiki Stick.
Pro's:
-Better Action (I mean much, much better)
-More sizes available
-More colors
-Best sinkrate for me! (Faster)
Con's:
-More expensive, but if you can afford it, go for it!
-Not scented (who cares? Do it yourself)
-Doesn't come with as much laminate/swirl colors
-Plastic is very soft
In terms of sink rate, I like the GYCB because it is faster than the other ones. In second comes the Dinger, then the Wave Worm (which is PAINFULLY slow). This is with a constant, 3/0 Gamakatsu EWG hook. I usually fish the Wave Worm with an additional nail inserted in the head.
