Clay,
I have three 85s. I have optilocs on two and Third Eye one piece mounts on the other.
Optilocs are good - the plastic ring insert prevents any marking. By using the right combination of bases and ring heights you can get the scope mounted as low to the barrel as possible. The only drawback is the screw between the ring and the base. This can work lose, and can't be tightened without removing the scope and mounts from the action. That is'nt difficult, but I use loctite for a bit of insurance.
The Third Eye ones are like normal one piece mounts, but with the Sako dovetail taper machined into the base. They're less versatile if you want to swap between different rifles. However, if you get the right set they are effective and hassle free. I got mine from UK Gunworks - very good firm to deal with.
Cheers,
Bob
