Dec Exam Choice (F8 + P…)

Hi,
I have failed F8 twice now (47 then 45) and so am going to retake this in Dec again and focus alot more on techique as I think that is what’s letting me down (I’m poor at written only exams)
I will be aiming for 3 exams in Dec and assuming I pass them (only F8 given me trouble to date) then I’ll try for the last 3 in Jun-14. (I thinking P6 (tax) and either P4/5 as options)

My question is, which 2 P papers do you think I should sit this Dec (along with F8)?
I’m currently thinking P1 + P3 due to the extra day gap between them plus I’ve read P2+P5 is a good combo to have left for Jun-14.
Thanks,
