I agree w/Fishless that sometimes it's best to stay with less selection possibilities allowing a better focus. I keep twister tails, tubes, swim baits and grubs in 1.5" to 4" lengths and mostly combo colors IE chartreuse/dark(blue, black, red, brown, etc) chartreuse/light (pink, silver, white, yellow, orange etc,). 99.999% of the time my baits and/or leadheads have a chartreause flavor. We go darker baits on darker days and vice versa. I think bait size, leadhead weight and line weight plays a much greater role than types of plastic.
But that being said, I admit I have have added a fairly new bait to the arsenal---Elaztech's Z-man Zinker-Z. I buy mine from Tackle Warehouse. (Hopefully I have correctly attached a rigging pic). I cut it in half ( to 2.5"), split the tail, super-glue it to a 1/16 to 3/8 oz (depending on depth). This is the most durable soft bait I've seen in my 50 plus years of crappie fishing. It is an amazing multi-species bait, the fish seem to clamp on and not let go. If I recall correctly, over the last + 3 years I've used it, the only species that swim in Kansas I have not landed on the Zinker are, gar, sunfish, carp, buffalo, bullhead and shad.
A week ago I found out 60# flathead eat them too! Talk about a battle.......
My last two trips for crappie have been very poor, but the only bait I could catch crappie on is the Zinker. It is a killer when casting it on a slow retreive for spawning crappie.
