My SX reels are my favorite. They are my preferred reels for everything from togs and flounder to big stripers and reds. I also have 2 mx reels that are one size larger. They have a faster retrieve, but I don't typically use them for rod-in-hand fishing so don't have as personal of a connection with them. They are fine trolling and live bait reels.
I can't say enough about my SX reels with the magnet cast control - very versatile. They are small and comfortable in the hand, yet they have great line capacity, plenty of power and are extremely durable. They are much tougher than their small size suggests, and they are reasonably priced for the quality (not cheap, but good value). They do have slightly slow retrieve, but that makes them powerful and ideal for a tussle. They cast great too! The Avet SX is a fine tool for a serious fisherman who wants to fight big fish rather than big gear!
