The pit at Ikea is indeed LB1, its a real free for all around there. I dont think its been fished properly for years due to all of the trouble, you were almost gaurenteed to be attacked/mugged/hassled on that water a few years back. The pikeys do like to patrol the lake and help themselves to your tackle.
There are much better options around this area, Bluebell as previously mentioned, also the lakes at Maxey, and Baintion fisheries are well worth a look. Nearer to home for you is Willowcroft at Murrow. Whittlsey also has a few good lakes worth a look. If you want a "Real" challenge and free fishing then have a look at the old brick pits at Eye, mega deep, mega hard !!
