I think it's too early to sell longs with the CRB likely making it's 3yr low now or very soon and with the dollar likely topping -- I'd guess (and hope considering my current positions) we see one more uptrend over the next month or so until the dollar puts in a new low this cycle, then looking to short aggressively as equities near their 4yr cycle top.
Of course, this has been a very confusing/volatile market, very difficult environment atm, especially with all the euro issues. The coming months are going to be very interesting.
