it was just a normal killstreak, not specialized or professional, so aka boring
Specialized and Professional Killstreaks for Rocket Launchers are grossly expensive so regular ones are acceptable

it ain't easy but i made a quackenbirdt one time
...out of a dozen times
It's how I got my AWPer Hand, Freedom Staff, and Ham Shank (as well as several Sniper melees from failed crafts)
