I just installed
Savarez Cantiga Premium 510 MRJP with
hard-tension basses and
normal-tension trebles (3rd is carbon [
Alliance] while 2nd and 1st are nylon [
New Cristal]) on my Yamaha N
CX1.
The result is a brighter tone with punchier bass. The carbon third eliminates the tubbiness of the 3rd string.
My preference for hard-tension basses is because I plan to use alternate tunings. The basses will therefore be down-tuned.
If you would prefer normal-tension across all the strings, get
Savarez Cantiga Premium 510 MRP. I use these on my flamenco guitars since they're always in standard tuning.
