I use spinning reels as well as conventional. These days they make them pretty solid. Don't see much difference in performance except....

When getting your drag pulled out on a spinning reel the line tends to twist up, even braid.

I can cast farther with the spinning reel but not that much farther then a conventional.

P.S.
I've used a spinning reel on long range trips to land tuna, wahoo and yellow tail with no problems. Personally though, I prefer the conventional reels.
