presently, the best signposts IMHO for playing traditional irish music on EC are the numerous air-driven instruments already deeply rooted in the irish tradition which are not "bisonoric" but are rather the same note both "in" and "out" (i.e., "unisonoric.") these include: flute, whistle, and pipes.
you are in a very nice position given your 15 years playing irish music on flute, provided you have thusly gained a firm grasp of the phrasing choices and staccato-versus-legato choices you can make while still remaining within the parameters of an authentic traditional irish sound; and provided you have gained a firm grasp of the kinds of phrasing or staccato-versus-legato options which might be doable, but wouldn't sound like itm. if you have gained a good feel for these principles through gobs of listening and playing, you can transfer much of that "feel" from flute right over to EC.
irish pipers, and whistle and flute players (and fiddle players as well) have to learn where the point is on the spectrum beyond which they're so "smooth" or legato they're outside the parameters of the irish idiom. they have to learn where to stop the air, or come off the fiddle strings, or to break up the line enough; or to lean ever so slightly into a note, to give the music the irish sense of lift and movement. same for an EC player.
there are always going to be purists who insist that free reed instruments shouldn't be allowed to play itm unless they are bisonoric. ignore them---this mentality is akin to penalizing the flute for not expressing the air like a harmonica, or expecting all fiddlers to phrase short-bow "sawstroke" style rather than the smooth, fluid, slurry "long-bow" sound which also is a genuine authentic fiddle style in itm.
unfortunately, heretofore many of the examples out there of attempts to play irish music on EC are efforts by people who have not gotten the irish style into their bones. i'm not saying you have to be born to it, but you have to have listened to it by the boatload for years to express it authentically on any instrument, and for whatever reason, lots of people attempting it on EC aren't that familiar with traditional irish phrasing "rules." you'll get it from the flute players, the whistlers, the pipers, and the authentic-sounding master irish PA players such as Alan Kelly, Mirella Murray, or Jimmy Keane.
regarding rolls: i use the "slap triplet" aka, the "Phantom Button" caper, along with so-called "half rolls" (same-note triplet with a cut inserted into it). to my ear, both of these maneuvers sound indistinguishable on EC from the way they sound on Anglo.
