So after much searching and reading many reviews on different models I decided on the garmin 800. It will be a big step up from my wired catseye. I got the bundle Since the main feature I wanted was heart rate, And I always keep track of my cadence even though now I stay in the 90 to 100 range without having to check. Also wanted the gps map since the roads we do our group rides on don't always have street signs and it will be nice to know if we have to turn when pulling
