I moved my funds to a 50:50 split between International Equity and Dynamic just over 3 years ago and since then they have both performed similarly when you overlay them on a graph (albeit the international fund slightly ahead). In comparison, the Balance fund only performed half as well.
I did consider the International Global Equity fund as it is based on the MSCI World Index which is a really good option and over the same period outperformed the other ones by a mile. However, this fund was not available as a standard PRSA (which may not be what your product is) and that put me off at the time.
Of course, if you are investing in equity funds, you need to be in for the long term (at least 5 years and ideally 10 years+); you only have to look at the recent market volatility due to Trump's policies.
