From the Accra Shafts website:
The optimum launch angle is around 12 degrees (+/- 1 degree). Slower swing speeds will need a higher launch angle. And higher swing speeds can afford a lower launch angle.

From GolfView magazine:
At 150 mph ball speed your optimum launch angle that gives you the most carry distance will be between 12.5 to 14 degrees.

From Frankly Golf:
The optimum launch angle / spin rate for a 150mph ball speed is 13 degrees and 2400 rpm

I also read numbers like the 16-degrees and 3000rpm numbers you quoted. I guess I have no effing clue what the right numbers are...
