In reply to Singleton_Alex:
Did you actually get any Fall Factor 1 or Fall Factor 2 falls? If so, I don't think they would not be difficult to count.
But ropes used indoors get quite a bit of abuse due to frequent lowering and falls, so I guess it's the sheath that gets your attention?
One more thing... it's your own personal safety, a retailer/manufacturer/instructor/whoever will tell you to retire it, your climbing buddy will tell you that you worry with no reason, but if you don't feel safe while climbing tied to it, you probably should retire it? Also, manufacturers (I believe) say that the lifetime of soft goods is 5 years of usage and 10 years of storage.
