I'm with Greg. Those are also the ONLY towels I'd even consider using for ONR. Shag-style (unlooped mf ends) towels are nice and thick, and I believe they'd do A LOT better job trapping any dirt particles than standard looped or waffle weave. They're also decently affordable when you figure they're around $2-3 bucks per towel. If you order some order at least 20 or more - they're worth it.
I recently got a shag-syle towel from Danase to try out. Despite the mf strands not being as long as on the Eurow - the towel feels twice as soft.
I would recommend the Blue Perl edgeless from Autopia-Carcare if you are seeking a waffle weave. I asked this question before and people recommended me that towel. Very happy with it.
And by the way. I find that if you surface is smooth and dont have too much contaminants on it, many towels work. However, I find a contaminated surface (doesnt have to be too much) is hard to dry even with a good towel.
I use big fluffy towels from Danase, followed by a regular Danase detailing towel. I hated the big fluffy towels until I realised I need to use them first, then the detailing towel. When I run out of big fluffies I use an old big blue waffle weave from CMA.
