well its called and optispark because the cam sensor is an optical sensor and it determines timing within itself.

The main problem is with the opti is has to run all the high voltage thru it which only contributes to it going bad.

If you want to really eliminate the problem with the opti, check out a Delteq system. It will eliminate the voltage going thru the opti and thus will increase the life tremendously. Also by going this route you don't need an aftermarket ignition system which will also save you some dough.
