Bob "Bud" Budesa knows me well. We have fished together numerous times, each leading & following. We each cast a little differently. We have each found what works for us, not only in casting style, & rigging, but rods as well.
I started out learning traditional style on extremely long belly lines & got to where I was able to pick up & cast 100 ft of line (off the reel) plus 15 ft leader. When I got into Skagit style, it was almost like starting from scratch. Especially that Constant Motion, Constant Load thing. Most fly fishers in my area nymph for steelhead, even the two hand guys. No one around here did Skagit style back then. Now there is Skagit style, & then there is what some refer to as "Edgit" style. I figured I may as well learn from the guy that figured it all out in the beginning, Ed Ward. So I bought the Skagit Master I DVD.
Ed got a lot of flack from everyone when he first started talking about his style of casting, even from fellow two hand guys on the Skagit river. And there are different opinions on the style to this day.
If you're like most, you learned fly fishing, & casting, on single hand rods. Life was simple. you bought X weight rod and X weight floating line to go with it, along with rod length tapered leader, some tippet material & that was that. Sink tips were seldom even mentioned. Some places you would be castigated for fishing anything but a dry fly, heaven forbid a sink tip
Welcome to the world of Spey fishing.
Each of these (Skagit & Scandi) styles have their followers, Jedi's, advantages, & disadvantages. The same can be said of rod actions. What suits one person to tee, won't work at all for the next guy. Is one better than the other? No, just different strokes for different folks. Pick a style, find a Jedi you can relate to/get along with, and forget the other style until you have the first one down.
P.S. When I fish a Skagit setup it is to be able to fish big, heavily weighted flies and not have to work my a$$ of casting them. For the waters & flies I fish, that equates to three to twelve feet of T-14. If not, I swap to what has been referred to as a Scandit, head & a conventional sink tip. In that respect the same rule that applies to any fly rod also applies to two hand rods. Choose the fly, choose a line capable of casting that fly, choose a rod capable of casting that line, in that order.
