Hi drumman,
Way cool u got a Zildjian K Custom hybrid! Welcome to the hybrid gang
I'm now really into this hybrid series.
Myself got a Hybrid 20" ride, 16" crash and waiting for the 11" splash coming in a few months. Enjoying them alot as its the sound i'm looking for and also their expressiveness(getting various sounds from the cymbals) and responsiveness.
Haha don worry about ur crash being loud, u can learn to control ur stick to play softer or at the volume u want.
Can also try using the tip of ur stick to crash. I know ur 17" crash would give a nice crash even when struck with the tip, as I've played with Plainsman 17" hybrid crash before. My 16" also performs the same.
Being loud is a good thing ya, cos u know u'll have the volume when u want it.
I refrain from saying the hybrids are loud, but i'll say they can be very loud. A better description is that they can cut very well. Plainsman would tell u that the hybrids are made for today's music that are generally loud.
The china is no different, (can be) very loud and very cutting.
Hav fun drumming!
Jonathan
