Cadence Speedo?

[AJ vd W]

I cannot decide between the Cateye Astrale8 and Topeak 140. Both has cadence, but the Topeak has Average and Max Cadence as well, is it really needed? The Cateye looks a lot better and has Manual Start/Stop that the Topeak does not have. I ride with MTB, but very often ride only road.

The other option of course is using both the Cateye Enduro8 and the Topeak 140. The Enduro also has dual trip distance and the pacer Arrow(why they didn't include that on the Astrale8 is a myth!)

Please help!!
