Yes, one does see a lot of negative comments about them here but mine seem to be working fine so far. I think if anything they are a bit too much carb (a pair that is)for the stock engines but i like the idea of secondaries on them so if you stay out of them they are about right and closer to a Rochester in CFM. What I don't like is the electric chokes but again, no real problems I would just rather have a manual steup.

Also a lot has been said about linkage problems but I had none and it was fairly easy for me, so go figure. What is easy for one is next to imposssible for the next person.

You asked for "professional opinions" but mine is just my own experience and I'm far from a professional.
