Theres a guy that has done a few youtube videos on it, I think he is a semi pro angler. The videos are filmed at Andersons Pro bait.
Go to youtube and search for Todd Steele, as well as a search for Anderson Pro Bait (videos are called fish church). I watched them a few years ago, its a start.
Also, be prepared for alot of current, you may not be used to this much. I'd suggest a variety of heavy jigs and a line that sinks, like braid.
I use an ounce, and sometime have a hard time staying vertical due to wind and boat control. People that jig better can propbably use smaller.
Many people use braid, as it sinks better and is smaller diameter, so cuts thru the water better.
Personally, I dont think the "river jigs" that are kind of aerodynamic looking cut down the resistance that much, but I think they help a little.
