And in this instance he's right.
Odiham is not full of fast jets wizzing around at 250 knots; the Chinooks based there come & go from training areas well away from the MATZ at low level. The only people flying there at the weekend will be the army gliding club & the ATC motorgliders.
Lasham sits inside the MATZ, none of their gliders ask permission to fly in the MATZ, even on weekdays.
On a sunny weekend you'll just be occupying an already busy frequency for no particular gain, all for less than 2 minutes crossing the far corner of the MATZ.
