i think it's called maxi brake or something similar that is tied tot he hyds portion of the brake.
you can also get a smart pendulum controller like a prodigy.. they work a lil beeter thant he cheaper 'timed' controllers.
that said. i have a timed hoppy and a couple drawtight activator 2's they 'work' fine.
i do have a prodigy in my 450.. it's nicer... etc.. cost more.. etc..
