Vector on Li-ion LC filter & 12v Stepup Placement advice.

Hello all... Just about to build a mini talon on which i will be building some Li-ion packs to run with it.
The Batteries i'll be using are ok down to 2.5v per cell so on a 4s pack the voltage could potentially drop to 10v... (not that i will be going low but just in case).
Just a quick question on the placement order of an LC filter and a Pololu 12v step up for the vtx.

When i wire the vtx with the 12v from the Vector what order do i place them in?? 12v feed - step up - LC filter - VTX or 12v feed - LC filter - step up - VTX or something completely different???

Cheers in advance Dave
