I like to tie my scuds using a very simple method - because I use them a lot, and lose them a lot. I make a dubbing loop at the bend of my hook, insert dubbing, and twist it into a chenille-like rope before wrapping it forward to the eye. I then clip the back and sides as shown here, and its finished. I also will add wire weight to the shank on some, before I dub the fly. When wet, this fly is very translucent and impressionistic.
I tie them in gray/olive, tan and pale orange. I haven't tried pink, but may based on Mick Hall's experience - see previous post below.
There are all kinds of scud patterns, so tie the ones that appeal to you, and see what ones work best when you fish them - you may already know this.
Sharpen your hooks!
