Ideal stats for pure pker

I just started a new char.. like 2 days ago and already have him up to lvl 51. I want to make him a pure pker but do not know anything about how high any of the stats should be, or even what stats I should get up...
His lvls are...
attack:42
strength:46
defense:40

any help would be apreciated.

 

shudnt have got def

 

Thanks for the answer
should i have left it at 0....because if so then i still have a few noob accounts that have all original stats that i can use. What about all the othere stats!!!

 

i suggest making a tanker from it
60 attack
60 str
90 defence
99 range
52 prayer

 

ok will do thanks for all the help!!

 

60 atk
99 str
1 def



Period. you can be 72cb if you keep everything else at 1, including magic and ranged.

 

get
45 def
80+ str
70 atk (For whip)
