UMM slotting avalanche and superior avalanche

[FullEclipse]

So mids reborn says I can slot a set of avalanche and a set of superior avalanche, is that true?  I just want to verify that is doable before i commit to the AH with my cash.

No, you cannot.  The planner doesn't have an easy way to block this, but it does not work in game.
