Josh Hazlewood believes the pink ball is a bit bipolar, while Ross Taylor says further investigation needs to be done on the viability of day-night Tests.
The third Test between Australia and New Zealand has delivered 25 wickets in two days of helter-skelter cricket.
There is every chance the Adelaide Oval clash will finish on day three. Cricket Australia boss James Sutherland has already flagged the prospect of two day-night fixtures being played next summer.
Sutherland is understandably pleased with TV ratings and crowds for the ongoing fixture - some 42,373 fans filed in for day two. But player feedback has been mixed.
Australia paceman Hazlewood grabbed 3-32 from 16 overs on Saturday night but was still coming to grips with the new Kookaburra.
