Shooter, I knew when I posted that reply it would be taken out of context......yes roll casting in general is a specialized style of fly casting and over sized lines would be the norm rather than the exception (I'm no stranger to fly fishing for bass in heavy timber and brush)....I was trying to help the average guy out there just beginning to fly fish for pan fish, trout, or other freshwater species where up sizing or downsizing would not be advisable when learning to cast effectively or correctly which can take some fishermen years to find their rhythm. There are no hard fast rules when it comes to fly fishing and alot of it boils down to specific conditions and personal style. For example: drift fishing from a boat often calls for full flex rods with drastically undersized or over sized lines to aid in mending the line behind the fly to achieve dead drift depending on current; or a dedicated streamer fisherman who might prefer a fast action cannon with an over sized line to punch those big flys thru the wind. There are rods on the market (and yes they are usually expensive) that are so well designed that even a complete novice could roll cast with relative ease or launch a big dry or popper 40 or 50ft. Wasn't trying to step on toes guys and I'm sure you fly fisherman down in Louisiana are great innovative fly casters.....I simply wanted to help the new guys......so I'll stick by my guns on my original statement.
Meet a resonable man halfway everytime....don't meet an unresonable man at all.
