Unless you are shooting rising birds/targets, such as box birds or trap targets, a high comb that causes you to see too much of the rib is going to be a great handicap to you. On other presentations you would be required to "float" the bird above the muzzle. This is not consistent with fine wingshooting.

I understood you wanted a hammer gun, as in "exposed hammers".
