Aircraft Down North Wales

[BoeingBoy]

There is no 'requirement' to operate down the straights at 1500' QNH. It's a request by Valley to give one thousand feet separation from fast jets coming out of Snowdonia. They pop up from the valley floor to 2500' for recovery hence you are 'asked' to provide that clearance.
I've never been told that I have to comply but there is an expectation that you will.

"EGCK AD 2.22 FLIGHT PROCEDURES

a) The aerodrome is in the vicinity of the Valley MATZ. Civil aircraft are to fly at 1500 FT or below (Holyhead QNH) in the Menai Straits area."

Don't shoot the messenger.

...fast jets coming out of Snowdonia.

That takes me back to the 60s. Standing near Llyn Ogwen, looking up into the cockpits of Gnats as they rolled and pulled down into the Nant Ffrancon valley.

Sad indeed, but it has to be said that there are worse ways to go.
