I found some information on them in Bogleheads. Anyone using them? Any advice? I think this may be easier as it rebalances for you. Thoughts?

A handful of ETFs-of-ETFs:
- AOA - iShares Core Aggressive Allocation ETF - 40% US equities, 40% international equities, 16% US bonds, 4% international currency-hedged bonds
- AOR - iShares Core Growth Allocation ETF - 30% US equities, 30% international equities, 32% US bonds, 8% international currency-hedged bonds
- AOM - iShares Core Moderate Allocation ETF - 20% US equities, 20% international equities, 50% US bonds, 10% international currency-hedged bonds
- AOK - iShares Core Conservative Allocation ETF - 15% US equities, 15% international equities, 60% US bonds, 10% international currency-hedged bonds
- GAL - SPDR SSGA Global Allocation ETF - 35% US equities, 40% international equities, 20% US bonds (including high-yield, cash, and TIPS), 2% international bonds, 3% commodities
- GAA - Cambria Global Asset Allocation ETF - 30% US equities (tilted to small, value, momentum), 25% international equities (tilted to value), 28% US bonds (including high-yield and TIPS), 10% international bonds (including inflation-protected and high-yield), 7% commodities
Of these, I'd go with the iShares. GAL and GAA hold 20+ underlying assets, and a lot of them seem unnecessary to me, such as the high-yielding bonds. (GAA's holdings make more sense, since it at least has factor tilts, but it also has few assets under management, at about $60 million.)
