Done that myself in the past. Can recommend. 20% cut, but feels like 50/50 weekend to workweek ratio indeed.

Another poster made this point, but I think this explains the different feel: you've dropped your working days by only 20%, but you've increased your free days by 50%. Even though it's still 4-work/3-off, it feels like a lot more.
