I can comment since I roast significant amounts of coffee as a hobby. Long story short: no, at least not for me. You can play around with roast level and get a variety of different flavors, depending on the bean. And at least for me, I keep a few large batches on hand (2-3 bags that are 65 lbs each). That's enough variety to keep me sated. Also, for most folks, if you have a brand new bean, you need a few roasts (or maybe, many roasts) to actually dial in a good roast profile. If you only buy a few pounds, you will run out of coffee before you roast it well enough to fully enjoy it. Then you start over again with a new bean.
