Spey casting looks very interesting for a number of reasons...for a guy like me the usually fishes ponds & lakes from shore, my understanding is that spey-casting allows you to keep your line in front of you during the casts, thus decreasing your chances of tangling in overhead trees, or brush behind you. Roll casting probably does the same thing, but it sounds like you can get more distance with a spey-style cast? I have to admit my roll-cast isn't very good at all...

The other interesting aspect is the additional distance you can theoretically get with a spey-cast. I think this would be useful for me when fishing the local reservoir, and the white bass start busting shad just beyond the reach of my usual fly-cast.

That being said...I've still been somewhat leery to purchase more gear.
