My experience with them is less then ideal. We experienced way too many short strikes to find them worthwhile. All the loose ends seemd to get the attention, which fell short of hook placement in the plastic.
We have found other plastics much, much more effective.
Can't say I've tried these but I have had some experience with Berkely Maggots etc... it would seem the old adage "Fishing lures are designed to catch fisherman... not fish" .. Would come in handy here.
I have always had great luck on Power Maggots. And many jigs. Although I agree - many lures dont catch fish. I think it is a fun challenge to catch fish on artificials - you can usually catch them on live bait.
I mail order them when I have to and empty out the store of them when they have my colors.
They FAR out fish tubes and twisters and other 1"-2" plastics. (in my experiance)
I vastly prefer the natural colors "toad" and "olive/shad"
rig them on a collarless 1/64-1/16jig heads with small enough hooks.
maybee not so much for bluegill but I have yet to find a more effective multispecies plastic.
I use these in just about every presentation but really love them slow trolled behind my kayak following a weed line.
Big enough to get the notice of laregmouth (in my experiance) and small enough to trigger active gills.
When focusing on gills though I do switch to other smaller/simpler plastics
FWIW: I have more bluegill lures than I could ever wear out / use up / justify; but I have a good supply of the power nymphs for a reason. I've had really good luck with them. During one period, one year, they absolutely wreaked havoc on fish of all kinds including channel cat. I probably have a picture somewhere yet of the rig I had fixed up with a brass cone shaped weight in front of a glass bead with a pink nymph on a chartreuse floating jig head. Admittedly, weird set up; but it was really effective for a while.
Also FWIW: I rigged up three bluegill rigs Friday night to have ready for next good fishing opportunity. One rod has a chartreuse road runner (probably 1/16th) with a pink nymph. One has the smaller size black and chartreuse Charlie Bee. One has a (maybe 1/32nd) black, gray, and white Grizzly Jig (upon which we normally impale a cricket) with a very small cork above it.
FWIW: Wife and I made it out to fish for a few minutes today. Her first cast with the chartreuse road runner pink nymph resulted in a big bluegill. A couple casts later she nabbed a big bass - which wound up breaking her line and getting away.
She then tried a swimbait with no luck while I tried the charlie bee with no luck. I rerigged the rod she'd used with a pink glow tube on pink head and caught a couple bass. I also caught a couple bass on a chartreuse / red titanium spinnerbait.
Oh yeah... Someone had asked me about the floating jig head. Actually, it was one probably meant for walleye. I've never found one specifically for bluegill - although I'd like to. That one was big for bluegill. It wasn't ideal; but seemed work for everything.
I have a huge supply of Berkley Power Baits in my bag in all assorted colors. I seem to always revert back to plain old white though. I started using them Steelhead fishing in the rivers here in Michigan tipping my Hare's Ear Nymph's with them. So I thought I would try the same for Gills. They work for me on the fly's as well as tipping them on small jigs for Gills, Perch and Crappie. I usually just leave enough hanging out the back for an extra attraction and like to think that the smell is what does it for the fish. Regardless, they come in handy little packages so they don't take up much room in the bag.
Decided to add... As much as I like and am a believer in the power nymphs, I do wish they came in a slightly smaller size. I did an impromptu comparison of several different lures last year and it did seem that smaller lures caught more.
