I placed the S-Hoop in top of a 12" Pearl Firecracker. The overall sound became more direct with a lot more attack and bass when hitting rimshots. Another good effect of this kind of hoop (all other sizes included) is more stability. The batter head stays better in tune, especially when you make rimshots all the time on the same place of the hoop. When this is the case, it is a lot more stable than a normal 1,6mm standard hoop.
I use this hoop in combination with different sizes of ring-dampers, which slide under the hoop and stay there even if you hold the snare upside down and shake it. Very nice and the snare becomes a very versatile and central piece of your drumkit.
I only can recommend to upgrade every snare with these hoops, because they have the sound of die cast hoops and create several possibilities of forming the sound plus the better stability.
