I used to have a real good commerical one that i got from a car dealer but lost it. i bought two new ones and they are crap, they bunch up and are not heavy duty at all.
I have been converted to the waffle weave microfiber, nothing better! BUT if you are to go with chamois the "Absorber" is the best I have used and I don't think its technically a chamois but it works VERY well! I still use the "Absorber" on my vinyl bed cover and wheels where the Waffle Weave might touch the ground and get rocks in it.
