Nah............ The M79 definitely needs artics. The route runs quite frequently and still artics fill up, especially in rush hours. Not to insane Bx12 levels, but it still fills up. Replace those artics with 40 footers and you'd either need boost service a ton or turn the M79 into one gigantic SRO clusterf**k in the rush hours.
The M96 isn't exactly perfect as is lmao. I don't ride it nearly as much as the M79+ so I can't really say much, but even off peak I've had buses where all it would take is one more busy stop and the bus would be packed like a sardine can//
