Getting 43 prayer is a good idea for training, but it will affect your combat level negatively for pking. To counter this, you may want to consider cannon training. You won't have as much hp, but it will lower your combat level, reducing competition. I'm not an expert on pking, so get some other opinions on this method before you try it. I did some calculations though, if you had 99 range and 10hp, you would be 65 combat. A dark bow spec would instantly kill at that level O_o.
