I would say, hold them both and see what feels more "natural". I prefer shorter barrels, just bought a 9.5" SRH thinking only of the "benifits" of a longer barrel, ... only to find I just can't get used to the balance of the gun. Im going to have it shortened, but should have known better as most of my Rugers are 4 5/8".
Hope this helps. And my .22 is old Gen 2 Colt Match Target Woodsman with a 6" barrel. But it balances great!
