which one to use

hey guys ...sorry if this is the wrong section for a stupid question like this but i never used a bot before...
for the past 3 weeks iv been grinding by hand for Sxp after i had to start a new character and its becoming more of a job than a game ,after looking through the forums i found allot of bots guides and mods but iam not sure which one to use ..which one is free?and works with the new client ? if you have any recommendation please let me know ...thanks allot for your help

RevBot RuleZ

i just logged off from game ...REV bot was cool ...better than i thought but it looked like it needs a baby sitter ..
the character kept getting stuck against trees ..and he runs to pick up other players items before he pickup his own ..and even if he is getting attacked hell just stand s there until he picks it up and wont attack bk ...do you have any of these problems..
