This would be my first suggestion, so any feedback would be appreciated.

B/O: 7.5

I was 1 of 1 on the market for the 6 days I had it on outpost.

Offers (Not including the ones without proof)

Burning Bonk Leadwear (6.5ish, about 5.7-6 with unusual overpay)

Roboactive Base Metal Billycock + Green Confetti Cosa Nostra (probably around 5.6 with overpay)

Green Black Hole Berliner's Bucket Helm + Purple Energy Hard Counter (Bout 5)

Cloud 9 Hat of Cards + Vivid Plasma Gym Rat (HOC seems to be about 5, Gym Rat about 1.8, so about a 6.3 offer)

Cauldron Bubbles Anger + Circling Peace Sign Firewall Helmet (Anger's about 7, price's outdated. so about a 8 offer with the helmet)

Also had a person willing to do a smoking KE + 2 buds if I add a bill's hat, I offered on their trade: http://www.tf2outpost.com/trade/15334304 (http://imgur.com/a/RQwyL) Seemed like he would be willing to just straight up do the KE and 2, but perhaps that's 2speculative4backpack.

As for what I ended up selling it for, the guy who offered the cauldron anger offered to replace the firewall with 1.5 buds. He ended up just doing 7 pure: http://imgur.com/a/oZBd9

So yeah, if any of my proof is bad, or the range is wrong or whatever just tell me.
