I rode B:TDK on opening day and found the zero-g roll to give no airtime and the corkscrews were very rough for a B&M. Many people have said that as the ride gets broken in the zero-g roll gets more forceful and the headbanging goes away. This doesnt really make sense to me but is it true? Did you find this to happen on other B&Ms?
I don't know how fast wheels wear out, but maybe you just had bad wheels. I think I heard somewhere that on some coasters they are replaced every day.
It's a new coaster so it is probably going to be a little rough and slow until the wheels get there break in. In mid season you will probably feel a difference in the ride. If you don't feel the difference then maybe thats how the ride is.
Coasters do have a break in period of usually about a month of regular operation. I found many coasters to improve greatly after about a month or two of operation!
