One challenge for anglers hunting for bigger trout, steelhead, bass or saltwater species, is casting a heavy fly that can make your fly line look more like a yo-yo.
In fact, I still don't have the technique perfected, and I've been fly fishing local lakes for bass for years.
Essentially, the key here is to avoid false casting, which is just going to make your line go haywire and scare the daylights out of any nearby fish - so the best approach is to swing your line over your shoulder in a nice tight line before your fly loses momentum.
Field and Stream has a nice breakdown of the maneuver in this month's issue, the graphics of which can also been seen on their website.
And when all else fails, just chuck and duck (my favorite casting motto next to grip it and strip it)!
Remember, it all comes down to practice, so the more you fish - or practice in the front yard - the better off you'll be in the field.
