I can't remember how they describe the maps on the box for 1,2,3.
Was it 1 sport, 2 extreme 3,??? then the 123 to fine tune each one.
I wasn't impressed with one to be honest, I went to 2 and the difference was fantastic, I may go over to 2+3 tomorrow and see how it goes. Over the next week or so I'll give 3 a go.
