The best way to nymph fish is to go buy a spinning rod.

I went fishing today, with a 8 weight and a 2 split shots, 1 between
each of the flies.

I can cast dry flies, I had a horrible time casting the line with 2
split shots. What is it, do I need to do a different type of cast for a
split shot than a dry fly?

I already have a spinning rod. I am wondering what the appeal of using
a fly rod to a spinning rod is...

(no one needs to tell me what the appeal of dry fly fishing is over
spinning, dry fly fishing is awesome)
