Pros:
A most impressive set of strings - the lower end in particular is a stunner. I haven't tried the Gold G yet, but the standard silver G is sonorous, deep and full of complex overtones. Straight out of the box it sounds great. Unfortunately the tone doesn't last forever, but these are still the best set of strings I have used thus far (currently one day into a set Peter Infeld with Plat E - too early to make comparisons but suffice to say the PIs don't have the same out-of-the-box wow factor). The normal stainless steel E is fine - sweet sounding yet has soom oomph too. More importantly it works in harmony with the rest of the set on my 1820s English violin without standing out - a problem often found with more powerful gold and platinum-plated Es. Worth experimenting with other Es though.
Cons:
None
