Jeff Lewis uses coils. he's very much not a fan of wound strings. last time I checked, he advocates pretty much what Bahauddin Dagar is currently using, which is a bit lighter than he used to use (Bablu tunes his vina to A instead of G# now):
main:#6.5 steel (used to be #7 roslau)
jordi: .028" phosphor bronze
pancham: .035" phosphor bronze
kharaj: .048" phosphor bronze (used to use .050")
high chikari: #2 steel (roslau)
low chikaris: #4 steel (roslau))
I experimented with tuning my vina to A, but opted to go back to G#. the negatives (harder to pull meends, esp. on pancham, a bit less 'heaviness', esp. on kharaj) outweighed the positives (main string seemed more 'accurate', perhaps the kharaj as well...). so I went back to #7 on the main, but have stayed with the .048" on kharaj - that miniscule (.002"!) difference does seem to make it more supple, which I like, without losing the 'weight', timbre-wise.
i.e. I wouldn't be a prospective customer for pre-cut strings, but thanks for asking!
