It depends on two factors, what you are cleaning, and what are the chacterisitcs of your extraction device. These two factors will determine the effective orifice size. You see, it's not just the dimensions of your wand lip area, but what is the effective opening when in contact with your cleaning surface.
A general rule of thumb for a portable adding a single blower, for an effective orifice below 3/4 square inches, select series for maximum air wattage. Above 3/4 square inches, you go with a parallel blower setup. The figure will change (go up) if you are adding to a machine that already has high CFM and lift potential. As such, if your wand seals well, go with series, if not, go with parallel.
If you are doing hard surfaces, the opening may be quite large with a brush ring, so parallel will definitely help. As well, a rotary wand with a hard suspension will also "leak" air at the CWI, so parallel will help there too. Conversely, a short run to a well sealed glided wand will benefit from a series setup.
I would go over your intended application, and existing setup with Mytee, so they can recommend the best option.

We have performed some digital vac testing to answer this technical question.
Assuming you are cleaning carpet with a 14" wand . . .
the Mytee 7300 Booster model we choose is based on two choices.
A Truckmount with #4 or larger blower will maintain higher lift at the wand,
and therefore we would choose the 7300-S with 225" of lift.
A portable, Electric Truck mount, or TM w/#3 blower would usually benefit more from the 7300 Plus with parallel 3-stage vacs.
As Shawn mentioned, the use of a rotary extractor or Turbo Hybrid,
would shift the outcome more in favor of the 7300 Plus parallel machine.
