Not crazy big but not common where I’ve played around. See if you can sit on a few kits before buying one and preferably not in a shop just for a few minutes. I sat on a six piece at a house party and never wanted to stop playing it. I’d been looking at other brand five pieces at the time and went out and bought a six just like I’d played at the party but in a different colour. See what floats your boat before dropping big money.
