Go ahead and complete your design and build a working prototype. And we will see which functions best. Surely you can build a better prototype than an unintelligent design?
Also, it should be noted that less than perfect functionality does not imply unintelligence.
A honda civic being slower than a corvette does not imply the Honda engineers were unintelligent. Likewise a Hummer getting lower gas mileage than a nissan doesn't imply unintelligence either.
We know man was created suboptimally. For we were created "lower than the angels" who have vastly superior bodies, judging from some of the feats attributed to them. Not only were we created lower, but our bodies were then redesigned specifically to fail.
