What to take with you now

Your pattern selection now is pretty simple, Drunella dun & spinners BWO's in size (short) #16, the dun's & spinners have a very prominent hump in their bodies so tie your flies a bit on the short length. I fished Johnson's last night and the dun's and spinners were on but not in the large number we normally see, this might have been due to the low humidity and they might have fallen later in the evening. I also saw quite a few Iso's but this is really not gang busters yet but will become a very important fly in the next few weeks, this is a main stay in the early to mid summer on Penns. Mixed in to the pot were some late season Cahill's both light and the very yellow one's, also do not forget the large stoneflies that are crashing into the riffles and creating a great feeding frenzy for our riffle trout.
  I watched one vey large trout feed almost exclusively on emergers, he never did take a fly off the surface, only a head and tail rise showing his tail on every rise but never having his mouth show, my best guess is BWO emergers or nymphs just below the surface, I could not get within casting distance, I'll try again tonight! The water is in fine shape, some color but not much but it is on the high side and us short guys have trouble getting around to the mid pool risers.
  One last note on the new Simms Vapor wading shoe- do not wear them in Penns- heck even with the aluminum star cleats they are totally useless, it's Spring Creek only for these shoes and back to felt for this guy in Penns.
Ok here is what you need in your fly box;
#16 BWO Emergers, Duns & Spinners (emerger colors vary with the stage of their emergence)
#14 Iso. Wets, Emergers & Spinners
#6/8 Dark & Yellow Stoneflies, bang them into the riffles
#14/16 Light & Yellow Cahills

Plus the kitchen sink if it will fit into your vest.
