Need to replace 10 y/o stuff, looking at the reflective cord and bungi. Are most diameters the same? I have an old poly tempest 170. I heard there are different strenth bungi cords also…thx for input…
Waiting to hear from Waterspyder on this as usual…he’s a lurker sometimes 
I just replaced mine
I used a drill bit to determine the size of the existing bungee cord. Bungee on my old Wilderness Systems Alto was 1/4". I ordered the replacement cord from NRS http://www.nrsweb.com/shop/product.asp?pfid=1842
Bungees are easy
I have ordered from NRS, MEC if you’re in canada, or most hardware stores will have it. Most common size i’ve seen is 1/4", some had 5/16". Just cut off the old stuf and thread the new stuff in. Just google a fishermans knot, it makes a decent looking knot for the deck.
The reflective lines themselves i haven’t replaced yet, so i’m not sure where you would find them
L.P.S.
New York Kayak Company
