Most common casting problems you see
When you are watching people cast (at a show, on the water, etc) what are the most common problems you see?
I would have to say that the answer depends on the region and the fishery. For instance most striper fishermen have a lot of creep in their cast.
I define "creep" as the rod coming forward during the backcast and before the application of power such that the rod is already forward before the cast begins. This has the effect of cutting the stroke to a very abrupt forward poke, which can not leverage full power of the rod and thus limits the available energy in the cast.
