PE2 both groups or IPCC both groups, please advise

Friends I've been appearing for PE2 since may 2008 unsuccessfully. My last attempt was in june 2009. (didn't attempt nov09) Now that PE2 students have one last final attempt in may 2010, I'm wondering if I should switch over to the new IPCC pattern. Classes and books that are available are more focussed on the new pattern than the old one. Because I still have both groups of PE2 pending, and also considering the poor pass percentage in PE2 results since PCC came, it all narrows down to wether the syllabus of IPCC is tougher than PE2, or is it only a matter of an extra number of papers. I'm willing to put in a wholehearted effort for whatever exam I write this May. I'm hearing that the results for the new pattern are comparatively better than the old PE2. I know that if I swith to IPCC, I can never revert back to the old pattern. So please advise me if I should stick with PE2 or switch over.
