Hi Snuf,
In my opinion you may have to rethink some of your ideas on snare drums.
I'm really not sure wooden shells produce a shorter decay, or that metal and wood built snares are destined for use in any given genre of music.
I guess I haven't thought about it too deeply, but I've used a wood shelled snare for one tour and a metal shelled drum for the next and haven't felt either was out of place. Likewise, no one's complained.
I think there are deeper thinkers on Drummercafe than me who can comment on the various properties of these materials. I tend to think wood snares are slightly warmer and softer sounding. Metal snares are slightly brighter, sometimes harsher, sometimes a tad louder. I really think it's dangerous to generalise though.
If you're in the market for a new snare, I would open your mind to any material and just try to find a drum you like the sound of.

When I was younger I always assumed that wooden snares were more-controlled, whilst metal snares produced lots of ring.  Now that I have owned a dozen or so different drums over the years, I've found that not to be the case.

I've found that mahogany drums are fat, warm with a nice, dry hint of ring.  They record great and are cheap to buy, especially the Japanese Slingerland/Ludwig/Gretsch clones.  Drawback?  You have to beat the crap out of one for it to cut through loud rock, and even then you won't be satisfied.  I can't say anything about the new run of Pearl mahogany drums.

I've found brass drums to be fat with manageable ring, lots of highs and plenty of volume.  Drawbacks?  None really.  I own a 14"x6.5" Pearl brass Sensitone that is my main axe right now.

Aluminum drums are fantastic.  Plenty of crack and ring, but versatile when tuned down.  Acrolites and Supraphonics are the workhorses of the industry.  Everyone should own one at some point.  I've one of each and wish I still had them.  Drawbacks?  Keystone-badge drums are started to go for a pretty penny.

Steel drums are loud with lots of ring.  The newer stainless steel drums are more manageable.  In fact, my dream drum would be a 15"x7" Keplinger stainless steel with diecast hoops & Nickelworks throw. But since I'm not rich, I'll just have to dream.

Don't know much about bronze or phosphor.  I have heard a bell-brass drum and loved it.  It was brutally loud with tons of ring.  Right up my alley.  And I've heard the Ochletree Paiste cymbal alloy drum and didn't find it any more special than brass.  I have untrained ears though.

I also don't know much about fiberglass, though I am eyeing a '90s era Fibes 14"x5" with extended snares up on Ebay.  The last thing I need is another snare drum but I want one purty bad.

Maple drums surprised me and converted me to wooden snares.  Maple is warm, with lots of crack and body.  I was surprised by how much ring the three maple snares I've owned have had.  I had a 15"x7" deep one-ply Radio King with reinforcement rings.  Beautiful drum that I got for a song, but I sold it to fund a down payment on our house.  Regrettable, but the house is more important.  The other two drums I currently own (a 14"x8" freefloater & a 14'x5" maple/gum/maple) are very versatile.  The 5" snare (a '90s Fibes) I've had a love/hate relationship with.  I still haven't found a sound I like when I'm on top of it.  Live and on tape the drum kicks ass.

I dunno about birch, jarrah or any of the other woods.
