Which FSA SL-K crank?

sarm34

I have a wilier XP Izoard bike with mainly 105 with the exception of the crank
http://www.wiggle.co.uk/wilier-izoard-xp-105-2013/ this bike this crank in picture
I have just had it swapped out for the ultegra compact which required another BB ( the old one had mega expo 8000/6000on it) as there was a little play in the BB when fitted, the new BB is a dura ace one , its an English tread fitting.....
now I don't like the look of the ultegra crank now its fitted to my bike, so I want to put a FSA SL-K crank on but which fitting am I supposed to buy? as they come in different BB fittings

It looks likely to be BS thread / Mega Exo but there's such a proliferation of BB standards these days i.e. BS Thread/BB86/BB30/PF30/BB386: I couldn't be 100% confident unless I saw a piccie of the current BB.
