ive used litecoinpool.org / notroll.in and ltc.kattare all of them work excellent when they work.
HOWEVER it seems that all of those pools get DDos attacked frequently...
litecoinpool.org is my personal favorit, however that is also the one with most downtime (popular Ddos victim?)
I have no chance of trying litecoinpool.org, it says that the registration for them is closed... I have used both notroll.in and kattare, I wanna test out give-me-ltc.com now. Thanks!
EDIT: Is it fine that it says "No suitable long-pool found ..." ?
