help needed: pedalchain with blender

[Low Sound Love]

hey guys

I need some advice. I got a few new pedals this week, of which one is an X-blender, so I need to rethink my pedalboard. The basic question is: help me map out a pedal chain. This is my gear:

(basses: gibson TB IV or Fender J w J-retro)

pedals
dirt: Digitech Bass Driver, Big John Obama Wah, EHX Big Muff, Boss ODB-3, Devi Ever Hyperion, Zvex Woolly Mammoth clone

preamp: Zvex SHO clone (I use it as preamp, always on, because I love how it breathes some air into any instrument) , Tech 21 VT Bass

modulation
EHX Neo Clone, Boss BF-3, EHX Bassballs

Blender: Xotic X-Blender

others: EBS Multi Comp, Boss Bass EQ, Boss TU-2

What I had in mind is this:
bass -> SHO clone -> X-Blender -(loop send)-> Woolly Mammoth clone -> Hyperion -> Big Muff -> ODB-3 -> Obama Wah -> Bassballs -> Neo Clone -> BF-3 -> Bass Driver -(loop return)-(Blender out)-> Multi Comp -> VT Bass -> Bass EQ -> Tuner -> amp

Are there any drawbacks to this layout? The only thing I'm sure about is that I want the dirt and modulation effects in the loop, and that into the VT-bass. Should modulation and envelope come before dirt?

Normally I'd take my time to just explore all possibilities, but I've got 2 gigs this weekend and no time for a time-consuming trial and error process.

Sorry for the long post, and thanks for any feedback!
