When on the Erie tribs I sometimes use #16 nympths/#14 glo bugs when there are low and clear conditions.I have used #14 on the SR and my go to hook for Glo Bugs is a #12 Mustad Egg Hook.I find early in the season my flash back nympth,PT,and the Prince does well on size#10.
As I always say it's the jntent of the angler not the type of fly that determines ethical fishing,if you're a lifter/liner you could use almost any fly.Ask Chartist,he'll tell you!
