Toss up between ZDC and ZNY, but they at least put all their traffic in trail (even if a bit tight). Our biggest gripe with ZBW is the side by side jobs they give us with the EWR arrivals over Shaff and Coate. I understand that at flight levels those DH8D's can't keep up with the jets, but when they get down low, they're trucking along at the same speeds. Most of us don't even bother say anything anymore. I just go "Shaff-EWR 69 go in a hold, volume" and hang up.
