If you 'pull the A risers (only)' in this type of location/conditions (behind a sharp change from steep slope to flat car park = airflow is ABOVE the ground so the wing needs to 'peel' UP from the ground and meets most of the wind ONLY once the leading edge is 3-5 ft above the surface) the wing's leading edge will tend to to 'roll over' in the early/mid launch stage... and go fully frontal once the wing is above the pilot!
It is important to EASE OFF any A's during the mid-launch phase.
When you watch me doing a 'Lazy & Efficent' launch you can (with luck/camera angle!) see how little of the launch is done with the A's 'pulled'/ and how little amount of A's are 'pulled'/ and how much of the 'launch arc' I have the A's eased off!
Note: on comp wings post 'bounce' (wing about to head up and FORWARD of my mass)) its (rough guide) A's on... Ease Off (35-55*)... Ease a little on (70-80*) ending with the comp wing up about (95-105*) up and ready to continue into gliding flight :-)
Why he didn't pull the A risers (only) and rise the wing till the zenith point!? He lose 10 min. without lunching..... :D
