I've been fishing almost 50 years and did quite well on the local tournament circuits I fished seriously for 3 or 4 years before I got burned out. I've never back reeled a spinning reel or thumb dragged (or whatever you call it) a baitcaster. I use quality line, set my drag properly, re-tie my knot as needed, change line on my reels as needed, and I don't horse a big fish straight to the boat. I've never seen the need for these tactics. If I didn't trust the drag on my reels I would throw them away and buy something else.
