1885 High Wall or 1874 Sharps?

[Ed333]

I traveled to the gun shop which had the lightly used Uberti Sharps this morning. It has a round barrel with a black matte finish on the barrel, ladder sight. I found it to be rather short in length of pull for me, and when I set the sight for 600 yards, I had to lift my face off of the stock. This will not do. Quality did not look bad, the wood to metal fit was good laterally, but a bit proud of the metal. Trigger was nice, case coloring was decent on receiver, the crescent was a bit more pronounced than what the photos appeared to show, although not as extreme as some I have considered. I left the 'hold' on it, give it some more thought, but I was not ready to go with it this morning.
I am 6'3" with longish neck and long arms, is a relatively short length of pull a common feature of the Sharps? I am thinking that a HighWall with shotgun butt and cheekpiece might be a good thing. I could always put an extender/padded sleeve on if the LOP was too short.
