I do like some of the changes,
2/2A seems like good changes to me, as does the 35 too.
The 36 Chester-Town End Farm? I'm not convinced on this one seems like a bit of Malarkey Marathon! In all seriousness quite a long route there. Giving Fence Houses a Sunderland link is a good idea though.
20/20A I'm not too conviced about either but could be okay if they manage to keep it to time.
Reducing the 56 could be a good move if it does help them keep to time more.
