I hsve a mint 20" sabian manhatten hh ride cymbal in excellent condition,not the newer hhx model that does not even compare!! dont have the weight on it yet,but it is super thin-great for jazz-getting harder to find these now!!
Also have a 20" paiste 602 ride in nice shape,tiniest crack off the bell hole which does not affect the sound in the slightest,this cymbal sounds great!
Also have a 60's zildjian 20" ride in excellent shape,nice patina
Let me know what you have,if you are interested,Thanks,Andy
