    AA1680 seems to be right between 2205 & 2207 so they maybe worth a try.
    the 240s seem to suck up just that little bit extra room though aye, even seated right out. its a bastard haha. id realy like to get the vitavouri 110 powder working if i can seeings we got a whole lot of it hahaha. but failing that, more experimentation on powders.
