It might be worth it to pick up a few models that you need, then sell the spures you don't need on eBay.
Hell, no! I magnetize the heck out of my models!
My magnetizing-rampage had its' pinnacle while building my XV8x Commander:
- The "hats" (Coldstar/Enforcer headshells) are magnetized
- The Coldstar Weaponry is magnetized
- The Thrusters are magnetized
- The Coldstar fins are glued
Hardest part was to find a pose which fits both characteristics.
Anyway, I know the box is not shipped before 10th of december but there are also no leaks yet on the formations' rules. Or my google-fu left me
