My buddy got into spey fishing several years back. I followed a year later. Not only is it kind of fun learning new casts, but fishing two handed rods has some major benefits. The most important to me is the ability to fish runs where there is little to no backcast space. With ten or fifteen feet of room behind you, you can usually hit the far bank pretty easily on rivers the size I fish. Watch how little room Andrew uses behind him while making a variety of different spey casts.
