Attack advice?

I got this account in f2p and I want to be a decent pker and KO with r2h. What do you suggest should I do with my attack and strength?
Should I keep my att at 50? should I get it to 60? or even higher?
To what level should I get my str to?

My tactics at pking - range and ko with r2h.

Stats:

 

Stay 50 attack, get 99 strength.

Range > G2H = game

 

Get the highest strength level you can be bothered to, and keep attack the same.

Maple short > G2H = win.

 

I'd work on the strength to about 90 or 99 would be great, keep att the same if you plan on staying F2P with range + R2H

 

Thanks, but wouldn't attack 50 be too low to k0?
Like hit 0's every time I try to K0?

 

get 60 attack

 

No need to level your atk up, it's fine.

Max out str then get g2h like the others have said.

It's like the best f2p ATM.

 

Stay 50 attack and max out str and go own
