My Force Shielder currently has 47/52 rate with merg ring, buff, kred and the default 5. I was wondering if either i should get a st pc helm and extend it to get 40/7 or buy a 20/3 forcy blade, currently i have a +9 20cd forcy blade and the trade off wouldnt be much, but however trading for a st helm i'll loose def unless i get it to over +11. With the helm i'd have 54/52 cr and 50/52 with the blade, was wondering what you guys would suggest i do, or something else perhaps?

Thanks,
