I own 20-25 combos, they value in cost and quality. On the majority of days I fish, I can get by with 3, on other days when the fishing is a little more tough, I might use 5. It is nice to have specific combos for different techniques, and multiples of some so you don't have to retie as often, but you can certainly get by without them and still catch a lot of fish and have a great time.
