Well, since I'm not sure how much racing I'll be able to do after next spring/summer, and with a lot of other things that I need to spend cash on, I've decided to stick with the HRM option, but I want to upgrade. I have a cs200cad right now and am looking for a wrist mounted unit (for cross-training) and the cool testing features, like ownindex/VO2max and others... I kinda like the Polar OwnOptimizer too. I'm looking at the Polar s725x and the Suunto T6. Right now, the Polar is leading the way because I can download data to my Mac (using 3rd party software) and it has a cadence option, where the T6 apparently doesn't. Oh, and the Polar is almost $100 cheaper.
I'm totally unfamiliar with Suunto's products, though--has anyone had any experience with these units, and how do you like them? Any issues with downloading to a Mac re: the s725x? Thanks.
