I’ve started using the maxim Platinum 9.8 mm rope. It is way better than a bi color in my opinion. The rope color is solid blue but starting six meters from the end two thread bundles turn red, at five meters four thread bundles are red, four meters from the end six bundles turn red until the rope is almost pure red at the end. The same applies to the middle two meters of the rope but with green. This provides an incredible visual of where you are on the rope. This is also the first rope where the sheath is physically woven into the core. This provides extra durability and seems to make it run like a much thinner rope. I’ve had mine for almost a year and a half and it still looks and feels like its brand new despite countless pitches in red rocks, Yosemite, J tree, the pinnacles and three months sport climbing in Europe. In my mind this is the new standard for ropes. This is seriously the best rope ever.
