I got the iStick Pico with Mini Melo III tank in the end, all the bits arrived today and I'm trying it out and it seems pretty good but I'm just wondering what you guys do when you want to try new flavours?

I've got 5 flavours here I want to try but only 1 tank, those tanks are about 20 quid a pop so I can't imagine you have to buy a different tank for each flavour so do you just bung the new flavour in on top of the old one or is there some way to wash out these tanks before adding a new flavour?
