Growers: why do you keep chasing new strains instead of perfecting one?

Been smoking 35 years. These days every time I find something I love it's gone in a month and replaced by another Cake or something ending in Z.

I just want the same good weed every time, not to be the test mule.

So for the growers here: is that coming from you, the dispensaries, or us? And when you get a cut from somebody, do you keep the name or make up your own?

Also, what happened to Green Crack?
