yes, even today, my unexchanged plus exchanged(i've been over at middlecoin til yesterday around payout time) is greater than what i'd get mining straight ltc to exchange to btc.  granted it isn't by a huge margin, but it's slightly better at the moment with several hours left to go.   and that would be if i was mining LTC at 100% PPS.

middlecoin had a crazy payout, check their thread.  that isn't an apt comparison for that reason
