You're right Wokka, I'm not having much luck getting a decent drum track together, I tried a couple of things but they weren't working the way I wanted them to, FL Studio seems to be more happy with straight 4/4 grooves than shuffles, it does have a "Swing" function but it doesn't get the shuffle I'm after, it has a roundabout way of changing from 4/4 to 3/4 and Triplets.
