I'd go for the highest possible exposure to diversified global equities, with the lowest fees. Usually 'managed' funds will have higher fees, most of which seldom justify them, often under-performing passive funds.
Your friend is only 49! His investment period doesn't end the day he retires (unless he intends cashing it in in full upon retirement). His investment period continues until he dies (hopefully a couple of decades later) or until the fund runs out (hopefully it won't).
Note: i am not an expert, and do not work in the pensions and investments industry, although i do follow the area closely with respect to my own pension and investments.
