I have a 5600 Tournament which is a 5500 with a thumb bar release and 1 more bearing (4) and it is bullet proof. I also have a Shimano Curado and as far as casting goes, it is superior to the 5600. No question. Both are on Lamiglas 8 1/2' 10-20 rods. As far as all around durability, drag and feel, I like the 5600. When casting light gear, the Curado has an advantage due to it's adjustability. It also dis-engages the line guide when casting, causing less drag. My 5600 also dis-engages the line guide, but I don't think the 5500 does if I remember right. All in all, both are great reels, but if I had to choose 1 for all my fishing, I would choose the ABU/Garcia. You own a great reel.
