/ Top roping with half ropes (Beal Cobra II)
Really not a suitable tool for the job. I'd buy the cheapest short single rope I could find.
Try gradually, progressively, testing out how far off the ground you have to be before you don't deck toproping on one half rope. I'd guess somewhere around 3 to 4 metres. Maybe less if your belayer keeps the rope so bowstring-tight that you're not actually climbing the route anyway.
Also, abrasion at the top would be a *huge* concern with a soft thin stretchy rope.
If I were you I'd probably just double a rope up and see how you go. A single half rope is a bit 'boingy' for top roping
I don't think so, they are on the edge of a beach, but to be honest, I haven't been there yet
buy a static rope or even better a Hauser rope.
by the sound or things you want something that won't take a dynamic loading and won't really get damage from sand
it's good enough for the sandstone in Kent (Harrison's, High rocks, Bowes etc.)
Buy a short single or climb with someone that has one. If you use the halves extensively they'll get trashed.
Various shops sell "wall ropes" of 20 or 30 mtrs for not too much at all. I'd get a nice chunky 10 or 10.5 and not knacker my half ropes.
If it ends up trashing your cobra thru abrasion, getting a new cobra (assuming you'll need one eventually for lead climbing somewhere else) will cost more than a wall single!
