Oldschool, you will not regret acquiring a nice Sonor tear-drop kit.
Sonor "Tear-Drop" aka "Shark-Tooth" kits from the mid '60's are works of art! The three ply European Beech shells with solid Beech re-rings are likely the thinnest out there. I measured mine at 3.5mm thick. The 12" tom literally vibrates visibly when struck and the sustain goes on and on...The slotted t-rods could be used on the space station to hold something important in place, they are that good! The rims are unique and add to the resonance of the shell with their enlarged surface area... German sound engineering and research again.
Furthermore, the tone controls on the bass and snares are mechanical works of art, with flawless function and precision...German engineering wins on just about everything..The only real weaknesses on these kits were the wraps and I agree, the cheapo plastic part on the snare strainer was a lapse in judgement. Most Sonor TD kits of that era have cracked or faded wraps that did not stand the test of time unlike the shells and hardware.
cheers!
