An early QSY to 630m WSPR?

As 10m FT8 seems poor again, I am tempted to QSY early to 630m WSPR.

UPDATE 1525z: Well it is done! I've QSYed to 630m WSPR (10mW ERP, 20%). It will be interesting to see what happens in daylight.

UPDATE 1550z: Several spots already given and received on 630m WSPR. My best spot (of my 10mW ERP) is by G4CPD (232km).

UPDATE 2246z: So far, an average evening on 630m WSPR.
