Questions
How does PCO 1810 differ from PCO 1881?
Both are 28 mm necks, but PCO 1810 is taller (about 21 mm vs 17 mm) and about 1.3 g heavier. Their caps are not interchangeable.
Should I switch to PCO 1881?
Switching saves PET but needs new caps and capper adjustment. If the line runs PCO 1810 and caps are in stock, it is easier to keep the current standard.
