Here I just bought this for my bass drum skin.
It offers its harmonic san no coverage, however, is still a need for a sound worthy of a bass drum.
I had a single skin (in clear) before so very harmonic but which was offering a strike stronger than that obtained with the coated powerstroke 4.
The price is 39 euro which is quite reasonable for a double fold of this size.
I board may not be the experience it takes but I think that would give clear even in a more slamming, and therefore more appropriate for styles that requires a good attack on the kick (rock, metal. ..).
