I like your thinking about the ideal number of blades, that will be my new mantra! I went for a hundred, like you i have always found them an excellent blade and go well with whatever razor I happen to be using that day.
After finding that most of my usual suppliers are unable to get Nacets i have bitten the bullet and bought in bulk from the razor blade club. With all the other blades i own i have worked out that I will have to live to an age of 312 to use them all! Assuming that i don't buy anymore!
