Hi Magnus,
I have two 22" Sabian HHX prototypes, both from the 2004 vault tour. One has kind of a TW/Bill Stewart character, but is lower in pitch and less trashy than my Johan nefertiti, which makes it great for smaller rooms where the Johan is too dominating. I once sent you a gig recording where I used this ride and you said you liked it

The other one is more of a modern mainstream ride that I have been using for funk/soul/party music with my big band. Both rides have great bells (solid, but fairly low pitched and dry), but this isn't very relavant in the case of you flat ride...
