An ”Almost Ready t' Fly” rocket,  raided exclusively for Hobby Lobby, that has a plastic fin can assembly and asymmetric fin layout with a rin' glider on one side.  I be unable t' get t' glider t' do anythin' but plunge straight t' t' ground usin' t' existin' shroud so a cut one out o' card stock that had a slightly longer tail, shiver me timbers, which ended up workin' great. Avast!  There is a version o' this with two rin' gliders called t' Double Ringer.
