I believe in singles too. But, I don't believe you can only do singles and stay in the game very long.
If you're only doing singles you are always on the edge of what your body and form are capable of doing. It seems almost inevitable that you will break down physically or make a bad form mistake and you will hurt yourself. Then injury recovery stalls progress while you rehab, etc.
So, I would say singles are great if you hitting them more than once and also if you are steadily increasing your volume with 80-90% too.
I guess I think it's a choice between hovering around 80-90% and increasing strength that way which is safer and somewhat slower, or jacking singles until something breaks and gaining top end strength faster, but having to accept some rehab as the price of doing business.
Which is better, a year to go from a 300 squat to 400, or six months to go the same distance, but then take six months off to recover from a bulging disc?
Obviously exaggerating, but that's what I think about the subject.
