thanks for all the comments; after a few more days of fiddling with it the comfort has set in a bit for the behind the
slide muting. And after hearing all the slide bits from you all, I realize the right hand muting is where its at to get a clean sing songy sound.
Control seems to be the name of the game. Just the right touch of vibrato, string isolation muting, it's not an easy bit in standard or drop D tuning.
At this point I haven't modified my guitar set up to taylor to slide playing. so with the thick walled pyrex, typically low action w/ 11's on it I don't have the breathing room to press too hard on the 1st & 6th w/o buzzing the fret. But my endeavor is fun.
