I put these strings on a Godin Multiac Nylon 7 SA guitar and love how they feel and sound. I use the low B string from a set of Pyramid strings for the 7th string. I like hard tension strings because I play mixed styles (Jazz, Fingerstyle, Rock, Bossa Nova, etc.), in standard and dropped tunnings.
To me the tension of these stings feels close to steel strings, but with all the comfort of good quality nylon strings. I drop the G string down to E, the low E string down to D and the A string down to G without any major issues. I even use a plectrum (sometimes) and a steel slide, and these strings handle everything better than any others I've tried.
It can be a "love/ hate thing" with these Hannabach Goldin strings, and I'm the kind of player that likes the sound of Thomastik/ John Pearse strings, and the Hannabach Goldins have a similar brightness to their sound, but the tension feels slightly harder than most high tension sets (which I like).
They may be a little too bright and hard tension for some players (especially for Flamenco guitarists) but they work great for my needs. They are a good quality, well made, unique sounding set, and I think they're worth paying a little extra for.
