About the raiser:
1. You may only use one raiser (usually Elbox recommends 2) and be able to fit indivision by the looks of it.
2. Even if you do use 2, the Mediator will work, my A1200 is the working proof of it (as 1 raiser wasn't enough for the BVision to fit), Mediator is slightly tilted, but it works fine.
