I completely agree with SSD. As someone who flies the LLR route regularly and also 'works' the LLR on 119.4 when doing my day job, I think it works pretty well as it is. By the way, the LLR IS class D airspace. Speaking as someone who was at the meetings to discuss the changes that happened to the LLR when it was re-orientated. I can tell you that AOPA, Liverpool ATC, Manchester ATC, and the CFI at Barton were all involved and many ideas were floated. At the end it was decided by all concerned that other than re-orientating it, to leave well alone.
Spiney.
P.S. if you regularly transit the LLR the Manchester Radar frequency changes on April 17th to 119.525. New flyers to the area may find this info handy.....
