Yeah there is no way I would flash recovery that I didn't download from xda and flash myself either from CWM or adb. But apparently some people did and it hasn't turned out well. Although others have and are fine. So I don't know.
Yeah I think there are 2 ways to go, but as BRD went the route of his own CWM and now is working with solarnz, I think if you want to install any BRD work, be it kernel or rom, you are probably better off going with the cwm aligned to his work and forget about Rom Manager.
