Many answers here.

1. Space in my pack does not matter that much. What matters is WEIGHT. Empty
bottles are trivial.
2. PET bottles are FAR more robust than a wine bladder (see my owner review of
them at BGT or on my FAQ).
3. Using PET bottles is far more convenient when cooking - single-handed
operation.
4. PET bottles allow much better weight distribution in my pack than a bladder.
5. I have been carrying a wine skin for the last 15 years (see my owner review
of them at BGT or on my FAQ).
