I have always been a huge fan of Savarez Corum basses. I think nothing sounds better on the C10. But I am not that fond of the trebles so I pair them with La Bella 2001 HT trebles or Augustine Imperial trebles. SBM allows you to buy bass and treble sets separately. HT La Bella 2001 set or Augustine Imperial blue set isn't bad either.
I've always felt that Cordoba guitars responded best with HT strings and have not found the strings mentioned above to be overly stiff. Somehow Cordoba's feel on the softer side even with HT strings, while some other guitars feel stiff even with just normal tension strings. The top thickness, bracing, etc. plays a role in how strings feel, along with action and neck relief. If you are finding the strings I mentioned too stiff, it's either because you're new and haven't developed the technique and callouses, or some adjustments can be made to the action and neck relief, or you just really prefer a much lighter tension. Even with HT strings on, the Cordoba's I've tried have all been very playable compared to many other guitars.
