Are you sure you're at 20%bf @ 160lbs? Thats an extremely light weight to be carrying around so much fat at 5ft 8.
At that weight I wouldn't worry about cutting at all, even if your bf% is near that. Eat twice as much protein, up the calories to 3000, focus on big compound movements and wait until you hit a reasonable weight (170lbs would be OK for your height), then cut down.
You'll find it much easier to lose fat once you've got a decent muscle base. Plus, as others have mentioned, its almost November now. You'd be far better off focusing on muscle mass now for the winter, then do a cut for summer starting next March/April. If you spend 6 weeks cutting now you'll only start bulking in December. Then you'll either have to delay your 2015 cut into May (which will leave you fat for the start of summer) or only have a very small bulking period - a waste of a winter.
