The Blue Water Canyon Pro Dual Sheath Rope - 8mm is a great canyoneering rope. The lite weight is great when approaches & canyons are multiple miles all day affairs.
8mm is fast on rappel so experts and thin people only. You also want to change the rub point on sharp edges constantly. 9.2mm is better for novices/intermediates, people who have more gravity mass, or if none of the above made any sense.
The orange color shows up well in pictures. The Dual Sheath has a great hand feel while on rappel. So soft that you wouldnt mind being tied up by a dominatrix with it if you are into that type of stuff.
Bluewater's dry treatment is the best I've ever used.
