We use a Horus ASLI (Angle Slope Level Indicator) through a Spuhr AA-0023 ACI mount to the Spuhr SP-4016 cantilever mount.
I like the Horus product because it indicates both the angle and the cosine. As far as I could find, competitors' products only indicate one or the other. There are, of course, other mount options, but we are very happy with our Spuhr mounts.
