What stats should I stay at [F2P Pure]

So i'm having a pure with 40 attack,70 range, 31 prayer and 72 str, HP 63. I was thinking what stats and CB lvl should I stop at? I've found that some people on my level have about 80 str and 80 range cause of no prayer. Please help ppl!

------IM NOT GOING P2P PURE, ONLY F2P---------

 

You should get 40 attack 90 ranged 99 strength and keep the 31 prayer level anyway prayer is not worth at low levels if you are f2p.

 

You should become a maxed Gravite/Gravite 2H Pure.

Best example: Here.
