#2 Are the extra pain and suffering required for your team to implement the system worth the possible benefit?

I think that the answer is very likely that for most teams and most game strategies, the extra benefit is not worth the cost, but that is not always the case.

It can be EXTREMELY important.
Since I'm the one who made the strong and somewhat intentionally controversal comments regarding multiple motors, shifters, "competitive" definition, etc... I suppose I should comment.

To meet the two "competitive" objectives:
A. Top speed of 10-12 ft/s and
B. A pushing force of 150 lbs.

This can be accomplished with any of the following:
1. 4 or more motors coupled together
2. 2 motors coupled with a multi-gearset transmission
3. 4 or motors coupled with a multi-gearset transmission

What is factual is that you can accomplish A and B with either 1 or 2.
Dr. Johnson has no qualms with this.

His concern from my understanding is that "competitive" is not universal. He gave two perfect examples of sitautions where the needs of certain teams exceeded that of A and B, and 1 and 2 would not suffice.

i.e.
If your requirements exceed that of A and B, or if you would like to be "extra competitive", option 3 can (and will) provide that.

My thesis is that for MOST teams, MOST of the time, in MOST games of the past, you could be "competitive" using MAINSTREAM strategies without using method 3 above. Because you could do it without 3, anything more than 1 or 2, I feel, is wasteful (over engineered).
