I went ahead a bought the Look system. (one pair for the captain)
I do a lot of my training on the tandem, and not having power data for that leaves a big hole.
I got tired of waiting on Garmin. Also allegedly, the Bluetooth upgrade for the Polar system will only require a firmware update.
So it may work out in the long run, if the do go low powered blue tooth, and that improves the head unit options.
If not, I at least have something to use in the interim, and can probably get a portion of my money back ebaying the Polar system.
I'll report back when I've gotten it installed and used it.
