I look at this the same way I look at automotive tires. If you drive a Porsche 911 GT3RS, you have about 10 options for a rear tire, and the cheap one is ~$300. If you drive a Toyota Corolla, you have about 130 options, and they start at $39. In this analogy, the ENVE 3-point-whatevers are the Porsche.
Folks running the Mavic system seem to be pleased overall, despite being "limited" to a certain selection of tires.
