There's no set rule or style for this. If you are starting out with a pipe and don't have much else on hand, of course open two or three tins and put them in rotation, and see which you prefer. Understand that you might really like some at first but they won't continue to be that pleasing, and others that don't click at first will grow on you. Some may need to be set aside in a jar and tried later. If you know one or two tins might reward aging, you might want to try that, smoking them after six months or a year, but usually this works better later when you have more blends on hand. I wouldn't feel too tied to a sampler as a set. If other blends catch your attention, put them in the rotation and see how they do with the sampler blends. Starting out, keep quantities small, an ounce or two in bulk tobacco, and a tin at a time, even when you find something you really like. Your taste will change and develop and what you think is terrific now may not remain a favorite, and blends that are hard to love at first may suddenly reveal themselves as great. Slow, slow. Let the experiences grow and develop.
Just wing it, you will learn by experience how it works out better than can be explained.
