If you are looking at this flight for hints on where to go in a WSW wind from Magic (Pen Cerrig Calch) number one hint would be Plan ahead to avoid the Pontrilas Danger area 20km down wind, If you want to know what the "danger" is, then google "secret bases pontrilas": -)
The North Devon wanderers (and country members of SEW) came in force, climbed high, crossed to Pandy ridge, and then had to struggle with a good breeze blowing every thermal towards Pontrilas DA. Good luck yourself.
