Monitoring through input on Print Track vs Master Fader

[jyellen]

My mix template is set up so that I monitor both my Surround and folded down Stereo mix via the Print Tracks while in Input mode. I was recently watching one of the Protools Expert videos where they mention this is not ideal and one should rather monitor via a Master Fader. However, there was no reason given in said video as it was off topic. However, this has piqued my interest so I was curious to hear from the experts why this is so. I'm willing to rework my template if it makes sense to do so :)

Here's a sample of my 5.1 signal flow:

dialog track -> 5.1 dialog bus -> 5.1 mix bus -> 5.1 Mix Print (monitored)

from what I understand the recommendation in question would be:

dialog track -> 5.1 dialog bus -> 5.1 mix bus -> 5.1 Master Fader (monitored)...as well as 5.1 mix bus ->5.1 Mix Print (via send)

Thanks in advance.
