Sarcastic Suggestions when using your 3 wt on the Beaverkill...
It is always best to use the 3 wt in the middle of the summer when the water is very low and hot. Trout like fighting in really hot water.
Trout fight much better on a 3 wt then a 5 or 6wt, so it will make you feel like you caught a bigger fish.
If the water is High even better , than when you are fighting the fish, if he catches a nice rapid, you can point your Rod tip straight at the fish and let him take you half way through your backing, then it will be a really good fight like Brad Pitt had in a RRTI.
Forget about all the technical stuff or what is in the trouts best interest, If the waters high and muddy, you will not be able to throw a big streamer with it, do it anyway, use real heavy tippet and chuck away, your rod tip will probably not break.
Oh yea and if you need to Nymph on the bottom in a heavy rapid with split shot , 3 wts are very effective for roll casting and chuck and ducking.
all kidding aside... you can catch a steelhead on a 3 wt, but do you want to? ( yea , I guess we all do, but you better have an extra rod with you )
If you are a great Caster your 3 wt will be fine for dry flies. But by NJ standards the beaverkill is huge, by catskill standards the lower beaverkill is still very big, the East Branch/west and Main stem are the only bigger rivers. By the way last year we had a drought , and the Beaverkill was half empty, so if that happens again, there may be no fishing the BK so this may be a moot point, and you may be forced to fish an alternate river.
My point is this, there are alot of variables when you go fishing up there, bringing a 3 wt is limiting yourself in MY opinion..despite my esteemed collegues on this board. If I was you I would go out and by a 5 wt, you should have one anyway.
Not having one is like not having a 7 iron in your golf bag. And the point of your trip is to have a good time not to go up there get overwhelmed , wind up driving to another river, and having an empty bag!.
Good Luck,
