I went for 12/27 since I have a +3 Bow (the 4 PD one). A faster bow and insane wpf lets you let fire a lot of arrows each wave. You can stay right near the top of the scoreboard for most kills as long as you get good at headshots.
At the really high waves, the build is a lot less useful. When you start fighting Vitez and higher, it takes multiple headshots to kill the bots. The majority of the time (early-mid waves) it is a very effective build.
I will probably go 15/XX or 18/XX next gen, since 4 PD is pretty awful if you are getting body shots. I could also set this as my strat character if I had more STR
