Russ,
I have been fly fishing for bass and panfish for most of my life. I wish I could say that I had all of the answers … heck I’d even like to have SOME of the answers. But I do have a little advise from some of my trials and (more than I care to admit) errors!
One thing to keep in mind is that Gills will eat just about ANYTHING!!! Most gills wil take just about anything into their mouths. But if it doesn’t taste like food to them, it gets spit out VERY quickly. Now with that in mind, there is no point in trying to use small flie for them, heck if they can fit it in their mouths, it gets eaten!!! Another good reason for not using small flies is that they tend to inhale the flies QUICKLY!!! Too small a fly, and you either end up killing a fish, or losing the fly to them!!! I try to go no lower than size 12 for them on dries, and now lower than 14 on nymphs.
Now for some help on fly selection. One of my all time favorites is with a popper. I have been tying some soft foam poppers that (I think) Mr. Castwell has shown us. It uses a dremel tool as a lathe for making some foam heads. Next to this style of fly, I have been tying (some rather ugly) dries. The patterns I have been using are Wulffs (yellow and royal,) Humpys (yellow and royal,) simple Adams (in body colors of gray, olive, or white.)
The top water stuff is very exciting, and a fun way to challenge yourself all day long. But if you are into numbers of fish, not just giving yourself the challenge, you can use a WIDE variety of nymphs! I have used BH and regular Princes, BH and regular Pheasant Tails, Gold Ribbed Hair’s Ear, and a fly I was shown years ago called the Chenielle Gnat. I have been using a fly shown on here known as Crappie Candy. I have been using it only a few months, but with GREAT success so far!!!
Now a fun thing to do, especially for late evening fishing for LARGE gills is to use a popper and nymph combo. Take a popper, and drop a clouser, or nymphs with similiar colors to the popper, about 1.5 feet below the popper. A lot of time I have found that gills might miss the popper on the first strike, then “find” it again as the clouser. I have used this to GREAT success in the last 30 minutes of light! I mean right before dark!!! The fun thing, and VERY hard thing, to do is to wait for the weight of the fish. You’ll find that you will hear the smack of the strike on the popper when you can BARELY see it. Instinct will tell you “fish on!!!” BUT!!! You have to wait!!! After a second or so, you’ll see the popper a little better and generally right about that momment, you’ll see it disappear!!! Talk about a emotional roller coaster ride!
Most of my bass fishing is done at the same time as gill fishing. Most of the time, I get bass on the popper and gills on anything. If I am specifically going after Bass, well I generally go with a popper (black, yellow, or white,) a Dahlberg Diver (same colors,) or wooly buggers (black tail with olive or black body, white tail with white body, or olive/white mixed tail with chautreuse body.)
Gills will eat just about anything, bass will eat anything a that is just a little bigger than gills can get to first.
Just my thoughts,
Reg
