Looking at those stats, I'm guessing that the Pro Mountain is really aimed for what you described, ie guiding. It obviously has less fall absorbing strands in the core (hence the lighter weight, less stretch and higher impact force), but the sheath would be more durable.
So basically if you aren't going to be falling a lot, but they'll be getting a lot of use, the Pro Mountain would be the better option and will last longer in terms of abrasion/wear and tear.
That said, I've never heard of that model before, it's certainly not one that is imported into Australia. |
