It is interesting to see quite a few opting in for the unmodded black filter. I don't think I will ever go that route, or even unmodded blue. I have, frankly, found the absolute apex that is to my tastes.
As Monty pointed out a few pages back, the folks at Shure do monitor users' impressions hence the advent of filters. I personally find this to be unsurprising but no less awesome; people like to tinker, customise and so on. People also like to have choice and flexibility. I am surprised in myself in that I do not have a preferred filter that corresponds with certain genres.
Removing the memory wire seems tempting, however I kind of like having the cable suspended away from the often sweaty underside of my ear. Look what that did to my IE800s. It is not in any way uncomfortable; in fact, for the most part these are as comfortable and wearable as my old IE8s.
However... I am slightly concerned about the constant piggy-tailing of the cable, which sometimes makes things seem weighty as well. Shure cables are known to be prone to snapping, hence I am leaving the piggy-tails (coiling) well alone.
