John, Okuma has been in business for many years. They are most know for their salt water fishing gear but in recent years have gained a reputation making fly fishing gear and freshwater spinning gear. The reels come in a 4/5 a 5/6 and a 6/7 I believe. The reels tend to run small so a 4/5 is perfect for my 3 wt. I use a 5/6 for my sinking line on my 6 wt. and it works fine. I have never used the largest size. Extra spools are available for all sizes. The White Elephant in Spokane offers them for about $20. I just prefer to buy another reel since they are so cheap in the first place. If you have any other questions, feel free to ask. Mike W.
