Gary,
thank you for this link.
I noticed they also have helical gears - this may be the solution to the problem as well, since helical gears have much lower short-period PE (because more than one pair of teeth are engaged at the same time, while with spur gears, it is only one pair).
I am not concerned with the number of teeth too much, since I have Standard EQ6 with Darren's mod - so as long as I am sort of close to optimal (step size etc) with reduction ratio, I am OK.
