Martin Era Strings - mk a difference

I've been trying out the new Martin Era strings 12-54 (MP540T) on my 000-15m. The tone is warmer than the MA540Ts, but the biggest difference is that the Era's are easier on the fingers with the flexible core technology (while string tension will be the same). I really like them but again given the warmer tone, need to pair with the right guitar.

Anyone else try these strings?
