airbrakes or crow brakes for 2m powered thermal wing

Hey guys,
I've designed a 2m flying wing, for thermalling and not so much speed.
The places I fly from I struggle to get a standard 2m sailplane down. are airbrakes or crow braking (flaps and ailerons opposed) better to get this thing down where i want it?

robbie- yep, crow brakes (inner flaps down and elevons up) will allow you to drop it comfortably into a tight spot at a high decent angle under full control. use the outer 60% of each wing half as the elevons and what ever is left over on the inside as flaps.

Just happened upon this one. Check out the April 2006 edition of RCSD, there's an article on four surface planks in it.
