Good Mother Stallards

I have a long post in the works about Rancho Gordo beans-- how wonderful they are, how they make me want to eat at least a pound of beans a week or more, but how I haven't yet scientifically compared them to non-heirloom dried beans.  But in the meantime, I'll simply say that I received an email today from Rancho Gordo about the new bean varieties available, with this link:

I hate when anyone asks me to name my favorite bean. Can you name a favorite child? No! But if I had favorites, I'd certainly have to consider Good Mother Stallards. Dense and delicious, they also exude the most perfect pot liquor of any bean.  Please prepare them simply and avoid the natural tendency to want to make them better by fussing about. Enjoy them without all the trappings to really get the most out of them!

There are still 2-4 pounds of Rancho Gordo beans in the pantry (about 25% of what I received as a birthday present 4 months ago).  Is it unreasonable to take these new varietals as an excuse to buy more?
