The 60/40 rule cuts both ways. You are also subject to daily market to market cash/margin drawdowns. It is probably easier to just buy RSP and then buy virtually any 'market' or tech etf/mutual fund to round up the top 10-20% weighting as you want it. The reason I say any will do is that there is little difference in the holdings of most of the etfs and funds.
