If I could only choose between the two I would choose the Centaur, both bowyers are brilliant, just push comes to shove I love a Centaur. And IMHO, its not that the Toelke is quieter, its just the carbon lams in the carbon Centaurs changes the tone of the shot to a little higher pitch is all. Shoot a glass Centaur it will be as quiet as a Whip. Speed wise, 'whatevs', yes the Centaur is the more aggressive design, but both bows will shoot outstanding either way. If you want a carbon bow, you will find none better than the Centaur. If you want a more 'classic' "warm" bow with a little more deep core slightly narrower limbs a Toelke might be your jive. Its Benz vs Beemer here. No wrong choice.
