The Prince Nymph was invented in 1941. Since then this fly has probably had 100 variations invented to match certain rivers/hatches, but they all originated from this original pattern. It is hard to really go wrong with this buggy looking pattern. The Prince Nymph is one of the best searching nymphs that I have ever used.
Many fisherman would select the Prince Nymph if they had to choose one fly to use. It is very versatile and it simply catches fish.
This fly is often weighted. If using lead wire, the 3761 hook is fine but if you use a bead you may choose to use the 5263 hook. It is a 3xl hook and can give you additional room to portion the body correctly.
Bottomline...tie some up and give them a try.
