To avoid the junk, in summary dominant hand is better for fine motor work - hopping and twitching plastics, less dominant hand is stronger - better for stronger work like single arm rows, one arm bench, one arm chin ups all that sort of jazz oh and brutalising fish. Just what you said you had experienced.
I changed everything over to lefty probs 5 years ago and only go back when I am ripping slugs for spottys, there are just some dexterous tasks that you need a dominant hand on the reel for. Wouldn't change back as I no one borrows my reels anymore though I can only blame myself for the scratches now...
Cheers Scott
