007 is not a "clean" strain. It is supposed to be fruity, dried raisin-like not far off from 002. That's the sweetness.
If it's to fruity for a palate switch strain.
I'd say it's like 002on steroids. But it need some care with temperature. It attenuates fast, but if you let it drop after main fermentation it goes on a semi-strike leaving you with a fuller, and somewhat sweeter tasting beer than it can be.
It's a great strain if you use it properly and want that british ale sweetness, but with a tad drier result. It needs to be heated up beyond fermentation temp to fully attenuate according to it's potential. So start low, and save the temps to the endgamde, if you start high, you will get a quite 002-fruity beer, but without the attenuation 007 can deliver. It takes of like a rocket. Don't let it fool you,raise temps or it will shut down as fast.
