Very True. But rod doesn't matter just need proper coaching on technique. Hank Patterson is the best at teaching beginners. Snap it.

Fortunately redfish can be forgiving and are great fish to learn on and don't have to be expert caster to catch em. Redfish in a feeding mode you don't have to always make a 40 yard cast with pinpoint accuracy with a heavy fly, but you do need something with some backbone when you hook up, hence 9 wt. Most of the time if you can put a fly inside the diameter of hula hoop at 10 to 15 yards and closer, you can catch a nice redfish as evidence with Mark's fishing buddy. A lot of times you don't even have to worry about a splash down if the tide is right, sometimes that commotion will make them take it immediately as reaction bite, especially if there is another redfish around due to competition. All you really have to worry about is not lining a fish.
But don't get me wrong, redfish can also be as skittish as a 20 inch trout in the Firehole river that has had every expert fly fisherman throw something at em but dynamite.
