Guys, I have the 12-pack from Autogeek. The 75:25's are blue...when you rub your hand against them, it's a "sharper poke" than the 80:20 green ones. The blues are for polishing and fine detailing, the greens are more for applying stuff and more intermediate steps (windows, etc). The blues are what I use to finish a car.
When you guys say "tight weave" are you referring to the "sharper poke" I feel from the blue towels when I rub my fingers against the fibers? The green 80:20's aren't as sharp.
Also, what is nap?
FWIW, I have some waffle-weaves from our sponsors, the 12 towels from Autogeek, and was looking at some TurtleWax ones from AutoZone. I have been afraid to buy from Wal-Mart or Target or any retail place, for fear of buying cheaper quality and screwing up my finish or layers.
