Polar RCX5 vs Garmin 310 vs Garmin 910

Need to upgrade. Garmin 305 when caput. Not sure if spending the money on the Garmin 910 is 'smart' although the swim gps is obviously great to have. Confused though on why 310XT cant' do what the 910 does for water distance and mapping! Any info on that?

The Polar is sexy (red is faster too - but I do love what my Garmin 305 offered so I may stick with Garmin.

I have a Polar FT80 for training clients and getting their HR, etc. But need a multi-sport watch again!
