Since your original set of foot were four different sprues of figures, one of each and the new mini-sets are four identical sprues, and you had a short life span of the sprues before they began to have flash and other problems, I have the following questions.
Are we to expect a production run of one fourth your normal sets?
Your cost for molds and such should be much less.
Does this explain why they run out fast when listed by stores?
I would say based on the feedback, this appears to be a positive development for Strelets, and we all want you to keep on producing more sets, although no two of us may agree on what the next sets should be.
