Your stat rolling techniques.

When rolling stats for a new character, do you have any particular techniques for quickly assessing if it's a good roll or not without adding all the numbers? How do you make your judgements of stat rolls as efficient as possible?

My strategy is to instantly click the reroll button if any stat is just one digit (unless all the other stats are really ridiculous) and also dismiss any rolls that are very close to the minimum for the particular race and class chosen.
