Best bot addon/RS client for PK'ing?

I remember seeing some bots that you could use which monitored your vengeance timer etc, just wondered if these were still about and if so whats the best one to use? Also, which client is best to use? Is swiftkit still the best?

Apologies, havent played for a while.. but yeah if someone could provide me with an answer that'd be great.

 

for the venge timer and hit predictor there are 2 scripts i know of on powerbot.
