I have been thinking on the same topic for a few days now (which is really the extent of my bitcoin thinking alltogether). I have debated back and forth on weather to mine Litecoin or Bitcoin. Right now I am mining Bitcoin, only because it is more mainstream. I am thinking about moving over, any suggestions on any changes I will need to make if I do make the transition?
Well, all I can say is that at the moment LTC mining using a GPU more profitable. Whether this trend continues going forward is anybody's guess.
Just my 0.000002 bitcoins worth.
