Yeah I've got the 10-pack of 530gsm's (the blue one's) from MF-Tech also. Good towels. I'm using a few of their waffle weaves too. They're okay, but not big enough to plush enough to really trap a lot of water. I think I have 4-5 of them. That's plenty to dry off a completely wet car though.
+1 for MF-Tech
