The PMO setup has never been a favorite of mine. The only reason I would ever select those ITBs would be if I needed that particular period look. There are MUCH better ITBs out there from a variety of sources. I prefer the AT Power ITBs as I prefer the benefits of the shaftless butterfly design (higher intake air velocity for any given air volume requirement which results in more power and torque). Plus they look super sexy. Finally, the PMO linkage setup is not great. The AT Power setup, for example, is much less likely to fall out of adjustment and is more precise.
Again, using the two DBW motor setup with most ITBs eliminates all the bell crank linkages and connects to the ITBs directly via a rod with rod ends. All super precise and with even lower chances of falling out of adjustment. Yes, it could be viewed as over kill but professional experience tells me otherwise.
In my case (a race engine in a race car), I was looking for the most power along with the highest reliability. So the extra cost was not really a factor. You, in your situation, may have less demanding requirements.
