also being a rehearsal studio owner, gusto ko lang mag share ng experience ko with cymbals...
ZBTs will not last definitely, specially crash and hihat. lalo na planet Z.
so far, eto ang mga nag last na cymbals na nagamit ko...
Scimitars, a year na yung hihats...the ride must be indestructible, grabe naman pag na-crack pa nila to...yung 16" crash gave out in 8 months ata.
a good idea para sa crash ay gumamit ka ng 18" crash ride, yung scimitar or edge ay ok at matibay, yung gamit ko na edge 18" almost half a year na, too early to say kung tatagal, pero makapal sya. i expect it to last at least a year...also, tip sa hihats...yung bottom ang lagay mo sa taas...mas makapal yun...less prone to cracking...alam ko out of production na yung iba dito...so good luck na lang mag-hanap...
i havent used B8s, cant comment on them...but since they're readily available, they're a good option.
also, clean them regularly. yung mga sweaty hands grabe mag corrode...imagine ilang kamay humahawak sa cymbals mo in a day...para hindi kainin ng corrosion yung edges...
oh, another thing i do is to never mount the cymbals too tightly..para free siya mag sway pag pinapalo...
hope any of these helps...
