I have a CII mod C with polar receiver. I'm very happy with both.

Mine is mounted in the center of the rail, 21 inches (53cm) from the
rear of the rail. I haven't had any problems with drop out.

The heart rate displayed on the CII is generally not exactly what is
displayed on the Polar wrist unit, but it is usually close (within 5
bpm). I think part of the discrepancy has to do with the time period
over which the pulse rate is averaged. The Polar seems to display the
avg HR over the last 5 seconds. I thing the CII uses a shorter time
BTW the CII price for the Polar Edge was better than I could find
