Whats your favorite fly to tie?

Which is your favorite fly to tie? mines recently become any type of pheasent tail nymph. tryin to make up different types. 

I'm with kyler, my favorite fly is the pheasent tail nymph, to use and tie, recently I have been trying to see how many I can tie in an hour, right now my record is 13, and that is not counting prep. time i.e. putting the beads on the the hook, but its fun.
 
I really like any fly that is not time consuming to tie that catches fish, I tie a fly that is nothing but peacock herl on a size 20 to 22 hook, fish that as a dropper and it really does the trick......and I can tie like 20 in an hour....LOL.

My fav. to tie is a Sulpher (Dry) I came up with. Nothing fancy really, but it's my own creation and it works well.
