I dunno whats happening but one thing for sure, everytime i try a mille, its bound to RTN(most of the time)/ STN.... all other acro seem ok for example tenuis birdnest and echinata(i think) but not mille... weird.. is there something needed extra for them... BTW do they need stronger flow than other acro
