In the northernmost part, the county of Cumbria, where I holidayed in the Lake District six years ago, the Boundary Commission's initial proposals have generally been rather sound and have considerable prior history behind them. However, I personally believe that the Cumberland, Westmorland, and Lancashire parts should be separated as much as possible for restoring community identity (there is nothing I can do about the ex-Yorkshire Sedbergh part, unfortunately; it really should never have been moved there). This can be done relatively easily.
My alternative constituency proposals for Cumbria are:
Penrith & Cockermouth succeeds Penrith & The Border and effectively recreates the 1918-50 constituency of the same name; I feel this is more recognisable than Penrith & Solway.
Westmorland succeeds Westmorland & Lonsdale by reuniting the eponymous county and removing ex-Lancashire parts from it and placing them back with an expanded Barrow-in-Furness where they actually belong.
Workington & Whitehaven succeeds Copeland, which was called Whitehaven until 1983. Unlike the BCE proposal it contains all of the Copeland area.
Next in this series: Lancashire.
