BTW - I have changed my TFSA "strategy" (I use the term loosely!). Previously, I liked the idea of having decent SA dividend paying ETF's in it to get the div tax savings. So no foreign ETF's. Did poorly and actually only grew by the dividend - which I reinvested
My thinking now is go for maximum growth and to hell with the dividend UNTIL you need to draw from it and then decide what strategy works best.
looked at DBWD and DBUS - went with DBUS as DBUS has out performed DBWD on every time scale so far. And although past performance blah blah blah, to my mind, it's still more concrete than future hypotheses.
