I really enjoy underwater videos. YouTube.com is a great resource to build confidence in how particular rigs work. I was curious about a chod rig, so I searched for it on You Tube. I found this video.
I am still not entirely sure I know what "chod" means and "PVA" is also a mystery, but I plan to research it more after seeing the video. I think using this style of fishing might help me with my casting confidence. During my last few trips this year, my casting has been pretty spotty. I had trouble getting my method to "stick" on the lead the way it should.
