I use Burris and I hear good things about Warne, especially if you shoot a heavy recoil gun. I shoot a Sako 75 in 7mm Rem Mag with a heavy Zeiss 6.5-20 Conquest.
I'm not sure about the newer Sakos but if they still use the dovetail style like my old L61R the Leupold mounts are great, very strong and clean looking.
