"Balanced" cylinder banks (A/F and EGT)

How cruicial is it to compare your front and rear cylinder banks A/F ratio and EGT when starting to modify your TT? I'm used to carbureted snowmobiles where you watch your EGT like a hawk, as one cylinder can go lean and ruin your day in a hurry. Do you have to worry about one bank over the other with mild modifications? I know a lot of guys only monitor the front bank because its easy to get at, and cheaper to buy a single channel gauge.
Its tough to find a "good" looking, space effective gauge that gives you 2 channels worth of data. I see a lot of aircraft looking gauges and they all look tacky to me.
Equus dual A/F
Analog dual EGT
Digital dual EGT
Note: I posted earlier about wanting to "match" all my upgraded gauges; chucking a nasty, Plain-Jane, lightbulb back-lit, black and white gauge will hurt the look im goin for. That being said, it ultimately comes down to Function, if I don't do it right in the first place, why bother, right?
So... do I need to monitor both banks?
THANKS from the Great White North!

...And if so, when? (What mods make it necessary to watch both sets of banks)

I only know a hand full of people who watch both front and back banks. The dual af you showed looks like it just goes into the stock o2's. Thats not going to help you a whole lot as its going to be very jumpy with only 1volt going to it.

Ya, those were just quick examples i dug up. It seems none of the main stream Automotive gauge manufacturers build Dual gauges to go with a matching set ie. Oil P, Fuel P, Water T, etc.

Is there any other reason to monitor both? am I going to experience fuel cut on one bank without seeing it on the other?

Unless you're going to do EGT on each cylinder, I would get a dual-channel wideband and call it a day. I run the AEM dual-channel UEGO (30-2300) and love it.

Having AFRs for both banks is much more informative. 12.2 from your single-channel and 12.0 / 12.5 from a dual-channel obviously say very different things about what's going on in your engine.
