1. Inkbrush: 287,652 points
It was the weapon I wanted to use the most, so yeah.
2. .96 Gal: 152,541 points
It became a weapon I really liked before the Inkbrush was released and I still use it often. I've tried the Deco version but it just doesn't fit me, I'm sticking with this.
3. Hero Roller Replica: 92,531 points
I felt like I didn't use this weapon much, but I guess I do. :p
And just because I feel like it, #4 is the Hero Shot Replica at 60,146 points. #5 is the Splash-O-Matic at 54,225 points.
