what do you guys use to measure...? I think a shoe lace is bad because it will add you a few cm..


btw this poll is not getting some belief .... the poll has a curve whcih tops at 6 inches.. and then gradually fell down.. but the 6.7+ is a mistery since it almost is equal to 6.3-6.6 :)maybe if i take 8% of the 6.7 is more accurate!
