the bell is a little weird, but everything else is nice! when i eventually get to drive buses, i think things like the versa would be the hardest! knowing my luck and driving style, the overhang will be a big problem!
the enviro's are a nice ride, but they don't take the bumpy roads well, K734DAO didn't either. i've forgot the name of the road now, but its as you are heading towards Hillcrest from Caldbeck Road. you turn left off Caldbeck road, and its that road that is the worst! i usually sit near the back of the bus, and the enviro's don't sound too strong lol. it also sounds like the gearbox could blow on some of them! not sure what its like for the driver, but quite a few times they have sounded like they don't want to change up! or they sound like an upchange will kill it!
as you say, can't beat the B10m's. well, some of them you can (K734DAO comes to mind! and 20107), but some of the better ones (K768DAO and P129XCN) are pretty good! the speed of the doors on K768 is a good point! last time i was on it they were open before you realised the driver pressed the button! doors on enviro's too slow!
