Be very careful with your ETF's. I got very badly burned with them recently as the spreads can be hidden.
This morning star article is well worth reading on the subject I read it too late. Also my ETF was geared with synthetic derivatives in it which almost killed it.
Total Cost of ETF Ownership: The Bid-Offer Spread | Morningstar
I do use the C fund for some monies but it's just one investment amongst others so like everything better to spread the risk round a few different options. None of the charges on the C fund though are anywhere close though to the 2% Dropp mentions most are 0.75%pa with no spreads due to the discounts Emirates gets on them. We just need more choice of them I think.
Happy firkin investment
