Pet Bowl or Resonator cone for bass

Question:
Hello Charles, I'm planning on converting an Applause acoustic bass guitar to a resonator instrument to get more volume out of it. Possible cones are your 7" Thunder cone, a 7" (m.o.l.) stainless steel dog dish, or a 9" (m.o.l.) dog dish. I was wondering which you'd recommend. Would your Thunder cone stand up to the downward pressure of bass guitar strings?
Thanks for your advice on this.
