Strings for Viola d'Amore

Information on available strings for Viola d'Amore is scant. I provide below a table of the available strings I have found thus far. Please let me know of any additions and corrections.
I considered gut strings a treacherous affair, with even less information available. The following sites have some data:

Playing Strings
Price US$
Thomastik-Infeld Dominant These are fairly widely used strings. They are with a synthetic perlon core and wound with silver. These strings can be obtained from major vendors such as www.juststrings.com. I have had some issues with a' and f# ripping out at the ball almost immediately after I put them on. Additionally the A string disentangled near the peg a couple of times. Thomastik generously replaced those strings. The sound is quite viola like, a bit piercing-sharp patricularly on the upper three stings.

7-15 each

Thomastik-Infeld Superflexible Also fairly widely available strings with a rope core. They are supposed to be a bit more durable, but also have a higher tension at the same pitch, hence will produce more strain on the instrument. I tried those as an alternative to the Dominant a' and f'# that ripped at the ball. The problem is, that the strings of the same pitch are of very different thickness, hence, can not be mixed and matched, because clearance for the bow is reduced to zero. The sound is also more piercing.

Pirastro Gut Strings

A through a silver wound with loop, f# through d" unvarnished gut without knot. Only sold as sets not individuals strings. Available at southweststrings. com and 123music.com.
The upper gut strings start to fray after 2-3 hours of playing, which seems rather quick. Tension is very inequal between upper and lower strings and ff-playing on the lower strings may cause them to touch one another. Gauges are interchangeable with Dominant.
