Summa summarum:

Practically no one wants this hat. This is practically always the last unsold hat in each trade and in a week it will most likely hit the craft pile. No reason to have 1.66ref flat anymore, because there are so many available for cheaper than that.

Constructive criticism and feedback is always welcome, so I'll know what to improve, if I happen to make new suggestions in the future.
