About those cages: I emailed the site, and the owner said he had a pair in daily use. They've held up. He does expect the cages to show scuffing where the bottle is inserted and removed. They also have purple, gold, and blue cages. They've got King straws anodized in green-turquoise and pink-purple fades also.
Not yet mentioned on the thread, but he
seems to have worked at Moots in the past.
