When I went up to Bob Jackson for BLB I talked to the builder there about the geometry of the BJs being a little bit more relaxed than say a Mercian, with more clearence - and he talked to me about path frames. He said it was a regional thing and in the past, when they built a lot of full team orders he would do many more Path frames for Northern England where grass track was/is more popular.
