I was in a pile of striped bass nearly as thick one time back when I lived on Cape Cod. Every fish was at least 30 inches, and most pushed 40 plus. My buddy and I were on his 14 ft Boston Whaler, and it was back when I nearly never fished saltwater on the fly (we're all young and dumb at some point). Nonetheless, I still had my only fly rod with me, a 6 weight. We were using our spinning rods and over an hour of sitting there, we only managed one fish between both of us which I pulled in on a slug-go. Frustrated, I picked up my fly rod and tied on a sand eel pattern while my buddy made fun of me and said it would never work. Needless to say, I couldn't cast without getting hit, and after my 6th or 7th on consecutive casts, my buddy was begging me for a turn on the fly rod. Of course, I playfully refused to let him use the technique that wouldn't work, but after my next fish, we traded off for the next couple hours until we were exhausted.
