The fund you're looking at is basically a world index tracker under the guise of active management (alpha 1.68 slightly beats market, beta 1.03 slightly more volatile). Its annual charge is 65bps which is not too bad, although a true tracker would be 10bps cheaper and deliver very similar returns. On the other hand, this doesn't seem to be an available option to you in your selection choice other than UK index which wouldn't deliver same diversification.
It's very heavily weighted to UK and North American equities. In the current market that's not necessarily a bad thing but could expose you if the market turned. Having said that, not sure the other funds you have available to you would perform in a non-correlated way (apart from the bonds, but they're not looking too healthy at the moment).
I don't think the fund you're looking at is a bad choice - in the range you have available to you I'd probably split between that one, the UK equities index tracker, and the default fund.
Not financial advice etc. Hope it performs well for you.
