It's a personal choice but I think the Cape Cook conversion is a lot more sympathetic to the original than the Cape Ross conversion, in which the original boat all but disappears.
Most sheerlines start strong (at the stem) and then sort of peter out. A while back I was looking for a sheer that is strong all the way through and found one on this Norwegian vessel.

A really good sheer (IMO) is a twisting sinuous curve of ever changing radii, a line to get lost in. It does not just go flat from midships aft, it's got perk at the stern. Most end up looking droopy aft unless there's a subtle little lift in the last few feet.

In Maine the powderhorn effect is called "Moose Shoulders" and can only be spotted from certain viewpoints.
