In 'soft' I can lift the wheel until third gear, but only intentionally - or if I am climbing something pretty steep.
One day I decided to try riding on trails in the 'aggressive' setting. When I went to lift the front wheel over a one foot high tree across the trail, the wheel lifted about four feet instead of the one foot I intended. 'Standard' mode as just a bit less. So I rode the rest of the day in 'soft'.
My impression is that power delivery is a bit more in quantity, but also significantly more immediate in 'aggressive' mode.
I think the map switch is great. I can have a fairly tame bike for the trails and more power for the pavement.
