Runescape help with a new account?

Just need some quick help. I have a lot of accounts. Range tank. Ancient mauler. Str pure. I was just wondering, what kind of account should I make? I was thinking about making a 5atk obby mauler with 45 def berzerker helm and fighter torso. I have a g mauler who is a little more developed, 40 atk 55 str. What do you think I should make? Any reccomendations would be great! And also I had this idea about a g maul tank? What are your thoughts on that? And you can reccomend ANY kind of account not just the ones I listed. Thanks!
