About how long will it take to get 99 strength in runescape?

I play about 6-7 hours a day on weekdays and on weekends about 10-12 hours a day and can train my *** off at I think the bandits or red spiders. I have currently 73 strength. What gear should i use if this isnt okay: veracs pskirt /sara sword/ and dscimmy/ d boots /glory / R.O.L/ cb brace/ helm of neit/d defender? Please give me some advice or approx. times for completion of 99 strength.
