Hi Aaron and welcome to the Community forum;
Doxey Marshes or Aqualate Mere seem to have been mentioned in the past for the starling murmurations although I'm not familiar with those areas myself. Also the Stone area.
We are based in N.Yorkshire so our info is not much use to you but around home the Starlings only seem to be gathering in small flocks of a few hundred and it is not until later in the year the birds gather in big numbers for spectacular sights. There has been a web site in previous years giving details of murmurations but I cannot remember who it was run by. It may be worth scanning the web for such a site or have a word with local birders who are usually on the ball with these details.
