The DG. Mag compass (not to mention GPS) can be uesd as a backup. If wings
are level and the compass isn’t moving, I’m ok on direction and bank.

DG (i have a compass, and a GPS with HSI yoke mounted).
Airspeed would be my next option. Again, GPS/DME Groundspeed, plus
pitch/power.
I’m going on a flight with a six-pack. My instrument of choice is a bottle
opener.

Hobbs meter.

I guess I need to be more specific. If, before an IFR flight, you had
to remove one of the instruments in the image linked below, which one
would it be?

Other than a compass, and navaid radios you have no other device to prevent you from impacting the ground unexpectedly. To be even more clear, you don’t have a GPS!

VSI.

The AI. In reading the FAA Instrument Flying Handbook, it says you can
derive all of the necessary flight information from the other 5 instruments.

But you can get all of the info provided by the TC or the DG from a single
instrument, and you can get all the info provided by the VSI from two.

Still VSI

I second that. The altimeter is more than adequate as a backup for the
VSI. And when you’re trying to damp out phugoid oscillations the
altimeter is actually better than the VSI for judging ascent/descent
because the VSI lags.

It was, and since Rod Machado doesn’t post here, I responded accordingly.

I was kidding. To answer your question, It’d be the VSI, as its legally not
required for instrument flight.
I’ve lots the airspeed indicator in IMC twice now and didn’t find it
effected the flight awhole lot. Both times were during climb out into
low IMC (stuck spring cover). However, if I had to pick, I’d probably
take the VSI. Nowadays with ok GPS altitude you could also lose the
alitimeter and make a reasonable attempt with the GPS altitude after
figuring out the difference from ATC’s mode C response.
The VSI only lags in giving a RATE of climb/descent. In smooth air, or
smooth pilot inputs, the VSI will give nearly immediate response up or
down.
I could live without the VSI, or the AI, or DG, and make do with the
rest of them and do a decent approach. I began teaching what I call
"Primitive Panel" over 30 years ago with a loss of gyros, then taking
away the Turn/Slip, the VSI, and leaving the student with little to
work with. They can do fine if they use their heads. Too many times in
over a thousand hours of actual IFR I’ve seen gyros fail as well as
other instruments and you had to extrapolate all the available
information. So far so good……

I agree, but the loss of any one of them is not that difficult to deal
with. The real problems start when you lose more than one. And if you
lose the AI, you’re probably going to lose the DG too.
Now if you have a GPS, all you need is the the TC. The GPS lags too
much to tell be useful for roll information, but it can be sufficient to
give you everything else. In a pinch. I certainly wouldn’t choose to
fly IMC that way, but it might be fun to try under the hood…

Given a choice of an instrument to smash, most students pick the hobbs
meter. The VSI is the usual volunteer however.
Who needs a VSI? Nice to have but not a necessity by any stretch.
That being said, if I had to go without anything else besides
the VSI, I’d next go for the turn coordinator.

Turn coordinator is the LAST one I’d care to give up. Remember needle,
ball, and airspeed practice on your instrument lessons? TC is almost
universally electric, which is an order of magnitude more reliable than the
vacuum pump necessary for the DG and the AI.
