I have decided to buy either a Garmin Edge 305 or Forerunner 305 and am wondering if anyone could elaborate on specific features/reasons that would sway me to choose the cycling specific Edge model over the running focused, yet multi-purpose, Forerunner. I estimate 80 percent of my use of this item will be for cycling, so if the Forerunner model's cycling utility is weak compared to the Edge model, I would choose the Edge. However, I am thinking my wife and I would use the Forerunner model for both running and x-c skiing. Unfortunately, I can't afford both. Any thoughts would be appreciated.
