CC Checker (LUX , 2check , 4check , viper ??

[smartguy]

Can someone suggest a reliable CC checker that doesnt really kill cards ...so I cant manually check each as that process is slow and tedious..
I have heard about Viper , Lux , 2check and 4check ..
Which one of these cc checkers are good enough to mass check cards and has a low kill-rate ?

LUX is BAD NOW it was GOOD not anymore
2check is best now
