I should clarify, I don't intend to sell it all every few years, I just may need to sell a little bit now and then (if i don't have to, great, I wont!). So it's more like long-term savings with bits and pieces used as needed... it is not intended as a "dump everything in, wait 3 years and then sell /use the money"
I think the moderate growth fund lifestrategy should work well.
