Hi Matt, I am right handed and always reeled with my right up until 2 years ago. Now all spin and baitcaster reels with lures are retrieved with the left and rod held and cast with the right. Spin rod butt is held free in retrieve and play for bass. For barra retrieve, butt is free for retrieve except for playing of the fish which is against the body and away at times. Does depend also which spin rod I use as one of mine has a longer butt section and is not as comfortable away from the body.
Funny with bait fishing,when it is done, I go back to right handed retrieve. - Richard
