Just got back from Borovets yesterday, perfect week, loads of snow, all runs were great, it snowed a lot, then the sun was out, great combination of all weather, no lift queues even though gondola closed quite a bit because of wind. So to you lucky lot going soon, you'll have a great time. The instructors reckon last week saw the best weather and snow conditions so far this season - lucky me I went in the right week.
