Obviously it is required to have as many useable and desireable gears as possible, Braden, but that doesn't mean I would like to have a car with 37 gears, does it?
More isn't always better because it overcomplicates and is more likely prone to al kinds of mechanical problems.
So ... that said ... there must be some kind of equilibrium ... some amount of gears that is enough to need and use and not too much to be unnecessarily complicated.

Personally ... I believe that 8 was enough ... 9 was just great and 10 is fantastic with small jumps between gears.
Would I go for 11? Not if it's heavier or more expensive ... because I don't see any use for that extra gear.
