how was your accident made worse? Did you endo becuase you have poor bike handling skills or did you stop to fast only to be rammed by someone behind you. If the former I suggest you use your brake more often if the latter then I suggest you avoid letting incompetent riders on your wheel.
Its kinda hard to argue that you can stop just as fast without a front brake or that ability doesn't make you safer. The ONLY way to ride as safely brakeless is to ride slower. The last bit was intended to be tounge in cheek.
