I don't recdall the exact figures, but it is close to half inch hard 
line, not quite as good, and of course a little more difference on 440. 
If your 9913 is still good, I wouldn't switch it.  I doubt if you'll see 
the difference.  Somewhere, I thought I found a page that listed coax 
losses, but if I recall, it listed so many and I didn't know what the 
numbers were.  I'll do some digging.  THe foam dialectrics have always 
had trouble with moisture and the 99913 is kind of a spiral with air 
space in there, so good place for moisture.  Agai n, unless it is bad, I 
wouldn't change it out.
