Martyn,
yes, actually my comment was commenting their reply to you. And I
understood that they just renamed the old KFN's and KFG's just KF's
without separating the two techniques. That is ok, if we think they both
have the same density. I also once tried the NP's, not good, quite
horrible...
I have also sometimes wondered, why there is so scanty information of
Savarez' products in their web pages.

Thank you Arto.
Did you see the reply I had from Saverez? It appears that over 0.95mm
the strings have a flouro carbon(?) or whatever core which is overlaid
with a thinner sheath/coating/winding(?) of the same material. I
presume this is done to increase flexibility (and elasticity?) of these
thicker strings.
Saverez used to make nylon strings overwound with nylon called NP (not
v good); I suppose these thicker sheathed/coated KF strings superseded
the old NP. Have you used them?
But isn't it odd that they, an established string maker, are unable to
provide a conversion table or factor? So thank you for your work.

Dear Martyn and others,
years ago I measured the density of KFN's and KFG's. I went to a
pharmacy and asked them to measure the weight of a piece of such
strings. Then I calculated the density of the material, knowing the
diameter, length and weight - using the "sub-calculator" of my 1st
version string calculator:
[1]http://www.cs.helsinki.fi/u/wikla/mus/Calcs/wwwscalc.html#P1
I got the density 1791 Kg/m3, which is clearly more that gut (about
1300
Kg/m3).
In my calculators I call these strings "carbon".
I do not know, if Savarez has changed their material since, but to me
this density parameter has worked well...
Best,
Arto
