Super congratulations on your wonderful stave kit. The sounds you're describing are no surprise to me, & if you've never played a well conceived & quality built stave kit, it's difficult to appreciate just how much more responsive they are. I especially like the sizes you've chosen, & yes, I guarantee that 20" bass drum will get a lot of use. It punches well above it's weight
On a general note, it's so good to see a player supporting a local quality builder with their patronage, & being so delighted with the result. You have something unique, that could not be bought off the shelf. We're not talking about a special veneer on a standard ply shell, or non standard size here, we're talking about an instrument of fundamentally distinctive voice & character, from a company that builds their own shells from scratch, not bought in. This is not an instrument where the buzz of discovery will fade quickly. Superb!!!!!!
