@JRA SBM is great, and the only US distributor for Dogal (at least since last year when I started using the Hellborgs—ironically in a search for a cheaper TIJR

but fell in love with them!) I only saw the Hellborg in one standard gauge, but heads-up on the SBM site Dogal has LowB
AND HighC sets so scan the gauges per string to make sure.
(they should really label it better.)
@Pyrrho Epoche Sorry can't help with the
finish of those sets. Is maybe what you're describing is the '
grippiness' of the wrap? I use to play nothing but DR about 20yrs ago, but always hated the wraps—very grippy on the hand. Is this what you're asking? For me DR, ROTO, and a few other Brands have an 'aggressive' outer wrap. I can say that if Hellborgs are any indication of Dogal wraps, they'll possibly 'smoother' than other sets. I thought they were similar to (but not quite as smooth as) TIJR.
Though, I can say after my experience with the Hellborg sets, Im very interested in trying their other offerings—like the Jaco and Nickel sets. I'd be curious to hear how the Dogal Nickels (or Steels) sound/feel.
