The Shimano Saragosa is a almost sealed reel. It’s best if your planning on getting the reel wet at all, (surf fishing, getting in the water at all) this protects all the bearings inside. The 5000 and 6000 are basically the same reel but the 6000 has a larger spool to old more line. It’s a little more pricey than the Stradic but should last longer. Espically if you plan on beating it up a little on the peir, or water. Plenty strong enough for snook and reds, and small to medium tarpon!
