The correct wax is key for powder and spring conditions. I haven't been out and have not heard of too much dust, but last spring we had layers of dust that once certain parts of mountain melted, exposed themselves. Usually pretty visible, but not always. If you randomly hit spots where to seem to slow rapidly, it could be a dust layer...Keep eye out for the off white snow. I have seen a few people bite it head over heels hitting dust patches.
Its April...just enjoy it while it lasts. I have never been disappointed going to Breckenridge. If it were just peak 8, with no alpine lifts it would be so so...But with Imperial/T-bar, there is plenty of terrain and soft snow. I'd be there if I could.
