Should i go for p7?

Hello friends,
I had attempted p5 three times and unfortunately failed… Now i m confused as p5 becoming more n more general and tougher with passing rate decreasing in every attempt and also i m unable to findout my loopholes to preapre more and strike harder in next attempt. I managed to clear p6 in last attempt. Now i want an advise that should i go for any other optional paper like p7. I know that in p7 lots of standards from f8 and p2 are carry forwarded and these two papers(f8 p2) i cleard in 2008-09 so obviously i dont remeber standards… Right now my preference i just to qualify acca irrespective which optional paper has more demand and which one is more useful for future.. If i continue with p5 for 4th time probably i ll attempt again with same kind of preparation but if i go for p7 it would be 1st attempt any any optional is not easy to pass in 1st attempt… Damn consfue 🙁
