As far as casting, you can take lessons, read books, watch DVD's, look
on YouTube, or all of the above. A basic fly cast is not all that complicated,
but some people can make it seem like brain surgery. Joan Wulff has a DVD
out that will leave you dazed and confused (I bought copy
3 part YouTube series will get you moving in the right direction: YouTube - Tight Lines-Learning to Fly Cast Part 1
There are plenty of other casting lessons on YouTube, but you have to separate bad advice from proper form. One example of less than good
You Tube advice is from a group known as Expert Village
. They have
64,000 videos on YouTube, and the flyfishing stuff is awful. Watch the guy
in that first link.
Good books would include Cam Sigler's Guide to FlyFishing
. Cam boils
things down to a very digestible level (unlike Joan Wulff), and has some
useful overall info. The Orvis and LL Bean guides to flyfishing will work, but I
really like Cam Sigler's book. Once you get the basics down, practice casting
in the yard and on the water. On the water casting practice can be done
separate from fishing. If you cast over the same area 10 a minute, any fish
that might have been there is spooked or long gone. Find a pond, and your
casting practice will have the on the water feel that backyard casting
doesn't have. That's not to say you shouldn't practice in the yard.
Hope that helps
P.S. Please don't beat me up for the Joan Wulff comment. I bought that DVD over the strong objections of a
great flyfishing women: Nancy Murphy. Nancy guides and instructs, and warned me that JW over-complicates
casting, but I had to pay $35 to see with my own eyes.
