As someone who owns the 22mm & 24mm Tsunami, my main problem with them is all the leaking. They both either leak from the top cap design or they inevitably start leaking from the 510 pin. And with Kennedy's airflow & topcap being separate, you don't get that w/o over dripping.
With it being a topper on a mech, you really don't want any leaking if you can help it
