Gotcha, fair enough. No one need feel pressure to roast to someone else's standard by any means. Again, I definitely think variety in green stock keeps things fun and exciting for what you get to drink at home (vs a more monotonous sole type of green approach). Again, it all really depends on how your expectations for coffee quality vs how your initial results (talent/luck) with roasting turn out. For me, I did such a bad job at roasting for a long time at the beginning, although the variety of origins/green tasted unique from each other, they all tasted similar in one regard: they all tasted bad, lol
That's not actually to discourage though, because if it's not clear, the core of the issue wasn't me using a variety of greens, but just not having a good working knowledge of my roasting equipment. In my case, switching to one green helped me start to really learn my equipment so that I could begin to use it in a way that (usually) produces good flavors across any given coffee I'm roasting. So, I guess you could say my green stock strategy was really more compensating for a general lack of skill in roasting, than it was about 'perfecting' my skills in roasting, haha.
So, by all means, don't avoid variety if having different greens around interests you. As long as the roasts are tasting good to you, you're good - that's the goal for all of us!
