Tjin,

Great point, but my Petzl Micro Traxions are rated for 7mm and my ATC for 7.7. I also often use water rescue rope or marine line for prussiks for better grip. That is, however one of the reasons for my question. I don't know how slick the coating on the Ice Floss is. I have used 8.1 mm for glacier line for a while and have been happy with it using prussiks or ascenders (I started with 7/16 Goldline). I like to use pulley's in my Z and have carried them for years (especially when 2 up). The Traxions make it even easier.

Your thoughts on larger rope poses a good discussion point though. The difference in weight for a good single line is not high. All my equipment will work on the larger line. The question is if the weight provides any particular advantage? Since my equipment and that of my colleagues will work, I am not sure I see any advantage either.

Thanks.

Respectfully,

Jerry
