The perception of the different maps varies per rider. I feal it only effects the bottom end and slightly the mid-range. One of my friends rode my 570 and thought it effected the whole rpm range. I ride from 5k to 12k el. As OhioPT says, it is very big difference at 11K. I leave it on aggressive most of the time. One ride I switched it to the soft mode in some tight, rocky single track as I was getting too tired to keep on top of the snap. I forgot to switch it back until I tried climbing a hill at about 11,500+. Incredible difference at that elevation. One thing for sure is you get better mpg on aggr. You can build your own pretty cheap.
