I know it has been at least 10 years+ a couple since I went left. Just feels better. I changed after a shoulder injury forced me to learn to cast lefthanded for the entire fall salmon and winter steelhead season. I liked not switching hands after casting so when I got healed up I went for a lefty.

Wife informed me the other day that her next baitcaster would be a lefty too. I think it has something to do with the experiance this fall with big fish and switching hands.

I like it cause I don't have to switch hands when things heat up.
