Q: This is a follow up to a previous question about USD ETFs where you suggested IWO for the long term small cap portion of a USD TFSA or USD RRSP. I'm curious why you suggest IWO in particular, as it seems to be a recurring suggestion. I'm partiuclarly interested in a comparison of IWO to IWM, VTWO, VBK and SLYG, how you would distinguish them, and in what situations these others might be preferred over IWO. These others all seem to have lower fees and slightly different composition features. Please take as many question credits as needed - thanks as always for helpful answers.
