Personal opinion ... don't like it. Prefer a flat look. However, I try not to impose my opinions on my customers. If they have seen that effect and like it the way you described, I screen the daylights out of the floor after sanding and before finish and that usually does the trick. When we distress a floor I 'over' screen it as well and start with 100 gt and screen again w/ 150 to ease screen marks to give the floor a realy worn look like this scraped walnut with inlay we did last summer

What say I?? If the customer likes it ... I like it. (But privately not too fond of it)
Good topic!
