I have a 905 with the 901 tip/cartridge I am trying the BLue filter pad and also the straw/silicon plug mods .
So far both work pretty well , the problem is that the cart. by design has the mouthpiece at 45 in respect to the breather hole ( I.E. drawing hole ) this allows the juice to creep into the draw hole and get in your mouth ( not great !! )
I think the design should have them at 0 deg. and mark the side that the hole will be on as UP with a line or ???
I dont know if this has been brought p before OR if there is a cart that is designed like this but I have been using the cart sideways and have NO BLEED !
