Obviously, the question is more complicated than it might appear and the solution is more elusive.
The time from making the decision on a material to delivering the product is too long for any of the 2nd batch suggestions. Trying to take orders and deposits and record keeping adds a burden of labor that I believe will add considerable cost to the project.
Since the next3 Mule Teams are already in progress, the quantities are fixed.
I'd like to thank all of you for the time, thought and suggestions. It is truly appreciated. They have given me a lot to think about. At tis time, We will assume that the MagnaXXX pieces were not typical and we will slowly increase the numbers of Mules moving forward.
We've added a "standard" version which will be generally available. We've added serrated versions to the project. I'm guessing that the Mule Team project will continue to evolve as we move forward.
