The reppe is awesome and the twill is awesomer. Seriously. I just got my green madder twill. The pattern of the weave is similar, small diagonal lines, though on my ties they are at different angles. And both have a similar sheen. The real difference is the feel and the drape. The twill is softer and less stiff. The drape is amazing. The three fold twill feels like a much thicker tie. I'll work on some pictures, but the difference seems to be more in the feel than the look. I really like the reppe ties, but I love the madder twill.
