I have been getting more into fly fishing in the last couple years (been fishing since I could walk) but now that I am old enough to actually afford fishing stuff I would like to get better at casting. I mainly just do float tube in some private mountain lakes, but like to hit a stream once in a while but leave too many flies in the weeds and willows. Anyone here care to offer some advice as to good videos/dvd/books or even live instruction in the North Colorado or front range Denver area? Or if you have tried videos you didn't think were worth it - let me know. I have some cousins that are pretty good and I enjoy watching them, but to them it's just kind of something they do and don't know how to explain. My dad is OK, but there are a few I watch and just go "wow - now THAT is just awesome! They make it look effortless." I don't want to spend $200 on books and videos to just hear "practice x o'clock to x o'clock while sitting on your lawn... I know the basics, I need someone that can tell me what I am doing right and wrong especially as I am moving from my floating lines to my full sink setup as the summer warms up and the fish are not rising as much now. My sinking lines are heavy and I can't get them to do what I want. Tired of slapping the water and tying my line in knots. Thanks.
