litecoin has been sleep for too long until now, and for the mining, my last mining with my hardware is in july-august this year and i don't see that there is a good result as i only have small hardware. maybe if the other have big hardware with big hashrate, the result will be high and they can save it into their wallet and wait for the best price of litecoin.
but its too hard to mining litecoin for now, i think better to mining small diff but there is a good chance for us to get stable profit. i think the choice is like flo, maybe gulden is also good choice.
Scrypt has the following coins for larger dedicated miners:
Litecoin and coins that are merged mined with it including Doge, Via etc
Gulden - Standalone
GameCredits - Standalone
The rest aren't worth mentioning as I don't believe they have a great future besides the odd pump here and there and 99% of the new alternatives won't look at using scrypt. Miners should support these 3 projects as best they can or risk one of them moving off the algo.
Mine litecoin for solid income, mine Gulden or GameCredits for future profits.
