In reply to Kerm:
I've had quite a few Tendon ropes, and the seem to be quite a solid option for those looking most bang for bucks.
Sure I've had ropes that have lasted a tad longer or felt a tad better, but more often than not with a hudge price bump. That said, I nowadays mostly just shop ropes that are on sale, eg. Bergfreunde has often quite a good bargains on their "own" models (i.e. bergfreunde edition, not sure if those are available on country specific sites though, you might need check the .de one).
I seem to more or less wear out a rope in a year or so, hence cheapo 10mm single is good enough for all the sport and craggin' I do. If I go on a bolt clippin' holiday, I do have a longer rope (80m). Same applies to winter and multipitch climbing (dry treated doubles).
