The thing I like least is that with or without the muffling ring the head gives the most dead toneless thud. You could actually use a wooden box rather than a bass drum and get the same sound. This is actually what alot of people are going for especially with mic'ed up hard rock/metal gigs so I can understand the popularity of this drumhead.

So it is a 10 for that kind of stuff 0 for other styles in my opinion, hence 5 overall, not that is particularly fair because it is a style specific head.
