For Fans of Flatpicking Guitar Magazine
If you play a D18-GE you must try out the Martin SP strings on it. I used D'Addario EJ17's for years. Richard Starkey (Nashville Martin guru) recommended that I try a set of the SPs after tweaking my Martin one day. He recently switched after years of playing EJ17s. They stay fresh longer, are more balanced, slightly brighter and the high end is silkier (to me anyway)...peace!
