The difference is weight and down hill performance. You pay a lot more for a little less weight, better fade resistance, and higher repair costs.
For normal Michigan ridding both brakes are way more then you need.
Both use DOT brake fluid which is need for high temperature down hill runs. The Elixer 1 uses Dot 4 which boils at 446 f, the Elixer 7 uses DOT 5.1 which boils at 518 f. Not a big difference. Is there a hill in michigan long and steep enough to heat a brake piston to over 400 degrees? When brake fluid boils, the brakes go away.
If you have not burned you rim brakes, then almost any disc brake will work for you. Look for a 2 piston self adjusting system. (less maintenance)
