I personally use the Cateye Astrale 8. It's really good. I got no complaints. This morning I tried picking up my cadence for longer intervals. It still feels ackward. A couple of times I went over 100 just to get the feel. But when I wasn't really pedaling hard I started to bounce on the saddle. I guess I gotta give it a little more time to get used to it. One thing I noticed was the ability to pick up my pace easier when I was between 90 and 95 and wanted to take it to 100+. However I didn't have my HRM on but it felt like my heart was gonna pop out of my chest.
