The only Cooper repeater I have is a model 54 (medium length action), it has a wood stock and a fluted 24 inch barrel. I am probably not as unbiased as I should be about it since I am a Cooper slut but to me the Sako 85 feels heavier and not as "lively" as the Cooper.
If you are anywhere near Prophet River Firearms they have quite a few Coopers on hand and you could get a feel for them there.
