Its been like half a year since I updated my strange count. Here's where I'm at now, by class.
Scout

"Wicked Nasty" Shortstop- 591 kills

"Server Clearing" Mad Milk- 2770 soaks
-Haven't played much Scout in the last year. I do like the synergy though between the milk and the shortstop. It'd be cool to have a strange mackerel, but they're expensive and really not worth it to me for how little I play scout.
Soldier

"Face melting" Black Box- 1353 kills

"Wicked Nasty" Shotgun-534 kills, 31 underwater kills

"Unremarkable" Market Gardener- 11 kills
-Black box is my primary strange for soldier. I only use the shotgun when facing pyros who airblast, or when I'm out of ammo with the box and need to kill somebody fast. I want to learn to market garden better...most of my current kills with it come from sneaking up on snipers.
Pyro

"Server Clearing" Degreaser -4026 kills (943 allies extinguished, 214 posthumous kills, 1750 projectiles reflected)

"Wicked Nasty" Shotgun-534 kills, 31 underwater kills

"Face Melting" Axetinguisher- 1012 kills, 216 full moon kills.

"Spectacularly Lethal" Powerjack- 295 kills
-I like using the degreaser on 2 fort near the bridge, since people jump in the water to put out the flames, and then I can score an underwater kill with the shotgun. My default melee with the degreaser is the axtinguisher, since the weapon switch helps with puff and stings. I'll use the powerjack occasionally, but only on maps where nobody is playing heavy.
Demoman

"Wicked Nasty" Grenade Launcher- 509 kills

"Epic" Stickybomb Launcher- 5021 kills (441 critical kills, 395 demomen killed, 94 defender kills)

"Somewhat Threatening" bottle- 92 kills

"Wicked Nasty" Scotsman Skullcutter -638 kills

"Scarcely Lethal" Eyelander- 30 heads taken.
-Sticky launcher is my first strange to make it to Epic. Skullcutter is almost entirely Degrootkeep kills. I recently got the eyelander, mostly to experiment with getting 4 heads and then being a fast, strong sticky demo. On a map like 2Fort I'll try and take out spies with the eyelander, and then once I'm at 2-4 heads, I can be really destructive with my stickylauncher.
Heavy

"Positively Inhumane" Tomislav- 806 kills.

"Gore Spattered" Natascha- 393 kills.
-I use the Tommy on offense or when I need to mobile, since Natascha takes too long to spin up. That said, I have more fun with the Natascha, and I like it defensively more. A lot of times I won't get credit for a kill, but by slowing down the enemy I can score an assist and help my team more.
Engie

"Face Melting" Jag- 1311 sentry kills, 110 kills, 484 sappers removed

"Gore Spattered" Frontier Justice- 492 kills
-Love the synergy between these two weps. I'll get a couple kills with my sentry, and then either destroy it or wait for it to die, and then I'll use the revenge crits to level up the FJ. They also have good synergy in that if I'm defending a point, I can shoot at a target using both weps, and I'll for sure level up either one of them.
Medic

"Sufficiently Lethal" Syringe Gun- 208 kills

"Rage-Inducing" medigun -1610 ubers, 4576 assists

"Gore-Spattered" Ubersaw- 386 kills
-Ubersaw has good synergy with the medigun. I don't use it much, but if I get a kill my uber meter is usually close to filled, so using the ubersaw helps me rack up ubers deployed. I need to work on upping my assist to uber ratio. So much of that is dependent though on how good your teammates are.
Sniper

"Totally Ordinary" Sniper Rifle- 999 kills

"Scarcely lethal" Tribalman's Shiv- 51 kills
-Haven't played much sniper lately. Considering getting a strange jarate/bushwacka combo so I can be more aggressive against close quarters opponents.
Spy

"Face Melting" knife-2301 kills

"Notably Dangerous" Diamondback- 157 kills

"Gore Spattered" Dead Ringer- 463 feigned deaths.

"Spectacularly Pseudoful" Sapper- 100 bldgs destroyed
-Getting a spy unusual hat, and a strange sapper, has totally revived my interest in playing spy. Now that I have more incentive to sap bldgs, my diamondback is getting more crits, and I'm leveling that up faster too.
