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?
Right now mining LTC with similar hardware will get you about 1.4 times the profit, due to the difficulty. Then you can use BTC-E to convert LTC to BTC.
Hmmmm...So what do I need to do to get up and running on LTC mining? (BTW I am doing GPU mining at around 200 MH/s)
