I have heard from many sources that the rapid fire is much stronger than advertised. It sounded at first that it would be a great fit between the fired up and the spitfire, as it has the FU core with a solid cover. But some even state that it is as strong as their gravity shift or shift. For those who have thrown it side by side with some other storm equipment, whats a comparison and how is the reaction shapes different. I am actually debating on drilling two of them up and putting different surfaces on them. One for sure pin above bridge, and the other to complement it? Any suggestions?
