I like TS-1 over the D97, but much of my findings on noise comes from built up loops that are waxed like crazy.
Imagine a wide paddle slapping on the water vs. a thin metal rod...which one will make more noise?
The effect is similar when you have huge hard string loops that slap the limbs on a recurve. So I make my TS-1 strings 14 strand without any extra in the loops (and I make sure the string nocks are well rounded so as not to shorten the life of the string loop). Each individual strand is more silky as well, than D-97.
As far as performance, when I had my chrony I had tested both strings and didn't find much difference in speed...if my memory is correct, then I think D-97 was a few fps on top.
In addition to the built up loops making a bit more noise...they don't fit in the string groove found on most recurve limbs as well as non-built up loops. I've found that the limbs have less potential to twist. Those string grooves are there for a reason and do help in maintaining straightness...if the string doesn't fit deeply into the groove, but instead, lays on top....it won't control the limb as well.
