What's been your experience switching from 32s to 28s or vice versa?
I went from 42s to 32s and then to 28s and was like whoa that's an over-correction so I went back to 32s. I was running Clement Strada LGGs and noticed a big difference in road feel/handling - mostly because I had to run significantly more pressure to maintain the same sag %. IIRC I was running 65-70psi in the 28s and was getting away with 40-45 in the 32s for about the same 15-17% sag.

Ya, you're most likely not going to be much faster but you will have to run higher pressures to get the same tire sag and as mentioned above you lose a lot of comfort and handling by going down to 28s.
If you're trying to be faster, work on riding in a more aero position and run higher pressures in your 32s.
ETA: Whoops - Missed you were running knobbies, ya go to a smooth tread 32 and you'll notice a huge improvement in speed on pavement.
