I'm not. The only thing that HR was telling me was that I hurt at 190 bpm... well, duh.

OP, get whatever you want. If you want lots of data, you can get it. If you're like me and find that you don't need all that data, you can cut back, too. Don't worry if you end up with a couple shoeboxes of unused bike accessories, because I'll bet everyone else here already has some.

I may give my Blackburn Neuro one more shot. The primary reason I got it was because it was immune to interference from my Dinotte headlight (my Strada Wireless only worked if I had the light set on High), and I figured that HR and cadence would be nice to see. I found that I could predict my cadence reading pretty closely -- being a musician helps a lot -- and it only took a few rides to see which level of pain equaled which heart rate. My main disappointment was that the batteries ran down sooner than I would have liked. I'm sick of changing batteries.
