Strong,stable,easy to use; sonic improvement only noticeable in recording. Good quality.
Pearl sizes for product are specifically for SET LUG numbers as demonstrated on outer packet :
8"= 5 Lugs per drum
10"= 6 Lugs (Same number for 12" & 13" Optimount.
14",15",18" ALL= 8 Lugs.
I was able to use 7-8" Optimount for 6",8" and 10" diameter Toms: they were 7-8" deep & although 4 LUGS ONLY; it still worked. I advise checking carefully your sizes- although some drummers say you can bend them to fit if Lug distances vary...I would not recommend that!
I do recommend this product.
