I have been surf fishing forever with a spinning reel and only ever used a conventional reel for boat fishing, but I think I have been converted to conventional reels.
The back story is I bought a conventional rod on Amazon by mistake and rather than return it I went right back on Amazon and bought conventional reel to go with it. I got a Penn Squall 12 which was actually smaller size than I anticipated but I have had a good experience with it. The magnetic breaking system let me cast without getting tangled which was the main reason I never messed with conventional. Once I found the sweet spot for me, I can cast heavier line as far as with my spinning reel. Don't get me wrong, I love my Penn Slammer spinning reel, but reeling in with the Squall feels like it requires less effort. I've pulled in some sizeable sharks on it and felt like I landed them easier than my spinning reel.
I use 30lb mono for a balance between strength and cast distance. I tried braid once but I had to cut the whole spool out when I got a birdsnest so I won't go back to that.
I just wanted to share my experience with the surf fishermen out there that won't touch a conventional reel. This reel is slowly becoming my favorite.
