Is it a matter of personal preference, or are there advantages to using different front-point setups on your crampons specific to what you are climbing?
For example, I'm still just getting into ice climbing and I have a pair of DMM Terminator crampons, which can be setup a variety of ways; dual front points, mono point, offset mono and mixed mono. They also come with bolt on heel-spurs, for doing things that I will probably not be doing anytime soon.
What are the advantages to these different setups? I understand that mono points are preferred for mixed and dry ice climbing, I can see offset mono points being useful climbing overhanging ice or ice columns, but could someone please list exactly what these different front-point setups were developed for?
