| This shouldn't be an issue on a ski unless what you are tying too is actually sharp. The loads we put the line threw are nowhere near threatening there structural integrity over less than optimal bends or getting near there braking strength, even with bad knots. Plus all the potential problem areas are readily inspectable. This is a real advantage of spectra / Dyneema over stainless wire rope. Wire rope is notorious for giving little warning before braking at the swage. There is a reason why sailors change there wire rigging on a schedule (or should) or take it in to be X-rayed. With Spectra line wear is visually evident. Even when screaming down the biggest wave and stomping on the rudder we only put 20-30 lbs of pressure (pulled that number out of my ass) and no were even close to the 600lbs braking strength of the Q-power line even if the knot compromises it by 50% and the line is worn half way threw…… let alone the 2mm Dyneema so commonly used (1600 lbs braking strength). I see no issues with Spectra other than it's inherent issues with compression strength and braid construction…. at least in a surfski rudder application. | This shouldn't be an issue on a ski unless what you are tying too is actually sharp.

| - | If you want to spend the winter perfection the best eye splice for Dyneema 12 strand, here is the appropriate splice. It's called the Modious Brummal Eye splice and is just weird, plus good luck doing this in 1.5-2mm Dyneema.\\ | + | If you want to spend the winter perfecting the best eye splice for Dyneema 12 strand, here is the appropriate splice.
