Just a rough idea, but it seems that every couple of weeks a 'what am bestist...(insert object here)' subject gets rehashed, so what if lists are compiled, like hop rubbers, tightbores, pistons, bushings whatever and they are stickied as polls so people can check one post to see what the general consensus is?
One badly worded idea for you - I'm sure it's riddled with holes
