Shoot for something like high 80's.
I already had a Sigma with cadence so when I got the 305 I didn't bother with the Garmin cadence sensor. I got a second sensor kit for the Sigma. It was cheaper than the Garmin cadence sensor and I wasn't all that interested in recording my cadence anyway. The Sigma gives me the my current and average cadence which is good enough. I use the Garmin for the rest of the data I want to look at.
