OK but nothing special

I have a Yamaha CPX900 which has quite a full sound with a strong bass response. I have tried Martin SP, which did not suit the guitar at all - too rich a sound, and Yamaha's AEP12, which worked very well - bright, crisp and clear, but allowing the full sound of the guitar to be heard. The Elixirs are somewhere between the two. They are a better match than the Martins and they are a little fuller sounding than the Yamahas, but not so crisp and clear. The Elixirs have a nice slick feel with reduced string noise and they should last much longer (but they are much more expensive).
