In reply to dg123: This subject keeps coming up or something similar and it isn't a simple subject to answer. All rope manufacturers make ropes which are suitable for different types of use.
It is correct that Beal ropes tend to have higher numbers of falls recorded and it is also correct that their elongation is greater but they are designed to do this resulting in the lowest impact figures which is ideal if being used on trade or marginal protection.
If you are thinking of buying a rope try and work out the activity that you are most likely to use it for and then try and compare the most relevant statistics.
If the main use is sport or indoor climbing then I would argue that impact forces are not too critical but if you are into trad and winter routes the the fact that Beal ropes have a low impact force and almost all of them pass the edge test makes sense.
The other factor that has recently been proven to give higher falls is the type and quality of dry treatments so once again this should be looked.
As I said not a simple subject.
