I hardly ever play my 10" Wuhan splash alone because it is so trashy. It also usually throws me off to hear how low it sometimes sounds. The 8", on the other hand, has a much nicer high tone to it.
They're definitely much thinner than some of the other splashes I have access to, a 10" Paiste 502 and 10" Stagg DH.
