Well, I haven't seen AV353 in a while. But, that seems to be on all the routes now. It had been allocated to the 68.69 and 151 after it's longish stint on the 92. EV64 seems to be out and about most days on the 68/69 and 151. It even made it on to the 78A a few Thursdays ago.
I haven't seen AX494 on the 65B yet, but I know it's on the 2 most of the time. AV418 and 419 can usually be seen on the 16s, AX545 cen be on any of D/Brooks' routes and EV88 and 89 can be seen on the 42s mostly. So, they do get about.
