I really like Climb Pro and I now tend to use the 830 over my 1030 because of it
What would make it even better is if the maps contained a database of climbs by name. My guess is that some climbs that have a short downhill section like the Croix de Fer might end up being split and having a database could help avoid that. These signature climbs could then be part of a set of achievements. Given that cyclists love to tick off these then I think it would be a really popular addition. There are websites that maintain databases already (eg ClimbbyBike) so worth looking into. Maybe a separate climb map like the elevation and base Map?
