Advice: Which BB for FSA SLK crankset (BSA)?
I just bought a FSA SLK carbon crankset but it doesn't come with a BB so I'd like to order one.
Here's a picture of it:

I'm unsure which BB to get with it...I'd prefer ceramic but item description talks about it needing a certain spline for it and I haven't gotten the crank yet to be able to tell which I need (nor do I know the difference between square and arc splines yet):
FSA MegaExo 8010 - ("square spline"...says it's for K-Force but other auctions include SLK)
FSA MegaExo 8681 - ("arc-spline"...says it's for SLK)
FSA MegaExo 8060 - ("square spline"...says it's for SLK)
The 8060 appears to be the one in the picture of the crank from what I can tell but I'm not sure.
From my understanding the 8010 is ceramic and the 8680/8681 are not.
Which should I get (or I am missing the correct one all together)?

If you can find the specific crank on FSA's site they tell you what sort of BB it takes. I believe the BB spindle length is specific to your frame. If you're having a bike shop install it I'd buy the BB through them and let them figure it out. I guessed with the BB spindle length when I got a new crank and guessed wrong. If you're installing it yourself, take the old one out and buy the same size.

I have a Chris King, and got the little grease gun tool. Just pump in new grease. I like it a ton better than the megaexo bb's. Those were nothing but trouble for me.

Any chance I could get you to provide a picture or model number for this? I know the seller had used a Chris King with it and said it was listed seperately on eBay but I couldn't find it so it must've went fast. At first glance the Chris King BB will probably be too far out of budget for now but it'd be nice to know what to look for if I decided to splurge on one. (Crankset was less than a Chris King BB)

...and one more bump for the Monday crowd that hops on here rather than working (I'm definitely guilty).
