I've had a 255 for about 2yrs now. The optical HRM is massively better than the 235. I now trust the HRM about 95% of the time versus trusting the 235 about 60% of the time.

Since you've established a respect for the Garmin product go ahead and invest the $120 (+/-) for the HRM-Pro Plus and do the HR the best way. Its more accurate that the watch.
