Do you love big bluegill?
The beauty of bluegill fishing is that many techniques are used by many different people and they all work. Fixed line, Tenkara, Fly, and Ultra-light are just to name a few. People fish with live, hard and soft baits, artificials, plastics, flies as well as lunch meat and they all work. The trick is to find which method works best for you. The good news is that most people on the site are willing to share information . The better news is that if you ask you will get much in the way of information . After that, it's up to you to develop your own style.
One lure I love to use is an in-line spinnerbait. Think Mepps, Blue Fox, Rooster Tail, etc. I actually assemble my own. I find I can control the colors of the blade/body/tail more easily, as well as the size/weight.
For Bluegill and other panfish, I've pretty much settled on a size 0 French blade spinner (think Mepps). Paired with a size 8 treble hook tied with white marabou, those get me a lot of fish every year.
That said, I have another model that I make, size 3 hammered copper Colorado blade, size 6 treble with chartreuse or olive marabou tied onto the hook. This one was intended for murky/muddy still water, targeting LMBs, but danged if I don't catch a lot of Bluegill with it!
The already-mentioned Rebel 7700 series crawfish crankbait is a must-have for all fishermen. Those things flat-out catch fish! So do the Strike King Bitsy Minnow. I prefer a natural minnow color, and a Fire-tiger. Natural colors for clear water, Fire-tiger for when the water gets dirty. I've also heard that a Chartreuse/Blue combo works good when the water gets a lot of algae in it during the summer.
If, and that's a big IF, you can find a Rebel minnowbait in the 1 1/4" size, I recommend getting some. Unfortunately, I'm not sure if Rebel makes those anymore; or if the Wally Worlds around here just don't carry them. Arkie makes a minnowbait that's almost identical. I wonder if Arkie bought the molds from Rebel????
I've been fly-fishing now for almost three years. I know you've said you're into spinning rods, but if you pair a weighted float with a dry fly, popper, or even a small weighted nymph, you can catch alarming numbers of fish like that.
That said, I've started getting into tying jigs pretty heavily. Small, 1/80th oz jigs custom-tied with materials/colors that I like have proven highly successful to not only myself, but several of my friends. Again, use a weighted float, put the jig about 18" - 5' below the float, cast out, and twitch it back. You'll be surprised!
You said you don't have a boat. I've been in your shoes for many years. Several years ago, I bought a fishing kayak. Much cheaper than a bigger boat, no motor to tag, don't usually have to tag the yak itself, just throw it in the back of a truck or on top of the car, and go! Cheap, easy, way to get off the bank.
I like to drift my boat about 15' or so away from the weedline on the bank. Most lakes here in OK have a water weed called "Water Willow" on the bank. I will cast towards holes and pockets in those weeds. If you're quiet, and watchful, you will occasionally see one of the weeds get a "thump" from below. I usually take this to be a 'Gill or Shellcracker trying to dislodge a bug. Sometimes, you will see quite a few of these weeds move, indicating a BIGGER fish hiding in the weeds. When I see that, I like to toss a topwater lure or a foam bug out. A LMB will usually slap it within seconds.
