Re: Rod grip style, and Lefty's principles
I use the thump on the top for distance and the pointing finger on top for short casting.
I watched lots of casting tips and bad casting videos on youtube and make sure I don't do that. I go with my own comfortable and relaxing style but still listen to positive critiques.
Someone, mentioned about the badminton grip. I played a lot of club badminton since I was trying to be a pro player in the men's double setup in my younger years. I use that grip when I am using the baitcasting reels.
