Wow, was it easy to find used racesills? Maybe I should put up a WTB thread.
I don't think I could live with a CF splitter as well. Is it common for people to grenade their splitters? Maybe I haven't been around long enough to see them post(if the post about it.)
I'm sure you know this already, but APC make a pretty decent universal splitter that you can couple with a chin spoiler like Lowtush's. You could also wait to see if there will be a rebirth of the NCI chin spoiler as well. I think that would be most beneficial.
