If one was to use it primarily with open sights, the hog-back could be cut straight and likely still give a comfortable cheek-weld for fast off-hand shooting.
Its a .45-70 after all, not a Creedmore!

Similarly, the Euro cheek-piece could be re-contoured to a small pancake. Several guys in my circle have done this with the CZ bolt-rifles and they look heaps better.

Apart from what degoins said about the O/U configuration, my main concern is the aluminium action, lightening the rifle at the exact place that weight needs to be concentrated to make the firearm a fast and responsive "lively" rifle for offhand work. I simply can't understand why makers of modern doubles just don't get this!!
Have they never even picked up a vintage British nitro double?
