I like to do a melange of Yirgacheffe (really my favorite and go-to). 25% beans roasted light/medium (City), 25% medium, 25 medium/dark, 25% dark (Full City+) just past second crack. 

I grind the beans into fine fine powder and use an unbleached paper filter. I tend to make it light with relatively low temps 200F.

Which one Eric? They make standard and "fine". I have and use both, and the paper filters, depending on the roast. I am curious how you like it.

Do share how you decide on the metal vs paper filters! Be very interested to hear how you do it.

I only just started using the standard Able Disk, on to my 3rd cup thus far, but I've also been using different roasts each time so it's quite early to tell. With the disk, I *think* there's more sediment, and I'm noticing that I need to plunge slower otherwise coffee spurts out the sides more so than with the paper filters.

FWIW I bought the standard disk because the barista selling it to me is a guy I trust, and he's found coffee to taste the same with both disks, just that the Fine is harder to plunge. Fine also feels more fragile, so I bought the Standard.

I typically get beans in increments of 1-2 lbs at a time, and don't really switch to something new until I am done with what I have. This encourages two of my favorite things: mild laziness and experimentation. The first few cups are typically paper filter, then "fine," then standard, until I find what I like the best. I also experiment with coarseness of grind and brewing/pressing time. I really just go for whichever filter lets me make the best tasting americano style coffee, stick with it until the beans are gone, and then start over.

I find that with darkest roasts / boldest beans the paper filter is best as the sediment tends to get in the way of flavor more, but I appreciate this is a VERY personal preference. One my friends prefers more sediment, esp with bolder coffee, so she always gets the standard disk when I am making coffee for her.

Generally, the scale works back from dark=paper, medium="fine", light=standard. A major exception is how fine/coarse I am grinding the beans, since the finer grinds will slip through (or get clogged in) the standard disk. Part of the reason I got the "fine" disk was I got so tired of using a 31 gauge wire strand to poke out stubborn coffee particles, and didn't want to grind too coarse.

My experience is the same on both points. I originally bought the standard disk to use more easily when backpacking (less waste, less stink in waste bag after 3+ days). I found that I could not press in the prescribed 20 seconds or whatever without moderate spatter. Then I figured, well, if I am going to be pressing slower, I will be brewing longer, so I might as well grind a little coarser. This reduces sediment and clogging but increases bitterness, which I do not love.

The fine is MUCH more fragile than standard, and I would never travel with fine as my only filter. All things being equal, I agree with your barista except for the point on sediment. Sediment and pressure can be modified using different filters and experiments with grind, filter type, and brew/press time are often rewarded.

Took a sniff of some premium ground Luwak/Civet coffee. Smells pretty rich and decadent tbh. Not going to try it though...

I've made up my mind to try a cup of Kopi Luwak before the end of the month. I'm not normally into Indonesian beans, however. They usually come off as too balmy and overly complex for my tastes. I doubt a bit of coon cat dung will help things by an appreciable amount.
