With all the recent hubub over combiners (a few excellent Devastators come to mind), I have acquired the "Radicon Itch" and wish to build one of my own. It will probably use exclusively animated figs. My question is in your experienced opinion what is the best method of combining separate transformers into one gestalt? Legos? Neo-Shifter joints? Rare Earth Magnets? Some sort of zoids piece? What is the strongest joint? The easiest to complete? the easiest to conceal (kinda important to fit in with the animated asthetic)? You tell me!
