-Are the newly produced BBs still made of brass?
Simple answer: YES, which alloy? Who knows, as there are a couple of thousand different formulas in the copper alloy family with over 300 hundred "brass" and over 300 "bronze" alloy formulas. Trying to figure the alloy composition out for a line of snares with as long as a production run as the BB has had is virtually impossible! With economics as a main driving factor you can sure bet that there is a fair amount of variety in Ludwig "brass." I have two modern BB's and they are from different alloy formulas.
The method of construction is what really differentiates the early and modern BB's. The early ones were of two piece soldered construction (#1 = top shell, #2 = bottom shell, #4 bead - point where the shells overlap) and the bearing edges were formed and soldered into the shell (#3A & 3B). Modern shells are spun and the bearing edges are flanged (there was a flange illustration in a recent post). See the images below (images from AK Snares which I annotated)

-Do you prefer die cast or triple flanged hoops, and why?
I like the die cast hoops, with its greater mass, as they are much more "musical" than the cheap triple flange hoop. If you doubt it do a simple test and suspend both type of hoops and strike them with a stick and tell me which one sings - it sure aint the triple. The die-cast hoop is generally louder, has a higher pitch, and way more sustain than the triple flange hoop.
Also there is some myth that needs to be put to rest, which is the notion that a die-cast hoop somehow "chokes" a snare. Heck the hoops don't even touch the shell, so I don't quite get how they would choke it.
-What is your preferred strainer for the BB and why?
I love the last version of the P-87... but it isn't "stock" on the latest snares, so I usually go with the P-86 Millennium throw-off as I really don't care for the P-85 in the least bit.
-Tube lugs vs. Imperial, any difference performance-wise or purely cosmetic?
Tube lugs for aesthetic reasons.
If you have any other comments about the drum, it's all MUCH appreciated. Looking to be purchasing one in the near future...
Don't buy into the hype that the "early" modern BB's from the 70's/early 80's are somehow superior to the latest ones or that the later ones somehow lack the "mojo" because they certain don't. There seems to be no shortage of folks willing to move up to the $2K mark those earlier drums on eBay but I really don't get why, as the construction is essential unchanged and the shell is still from "old growth" copper alloy, so why pay a premium for a drum that is still in production. I say get a new one and make it personal - make your own memories. Now if you're looking for an investment....
