Replying to Skis for my dad!

OK my dad wants some new skis. He is 5'8, 140 pounds and an advanced resort skier. He doesn't want twin tips, he wants an "all mountain" ski.
He wants the best performance from the ski on black (diamond/double diamond) runs, which are often mogul runs. He currently owns Salomon x-screams from back in the day in a 169.
His prioties are:
1.Good performance in bumps
2.Good performance on piste carving
3.Decent off piste and in powder.
i would think something along the lines of the old Rossignol B1 or B2 maybe? But i dont know much about the newer ranges in that kind of line. Oh and please can nobody recommend any of the following: invaders, anthems, ep pros, hellbents, jjs or any of the other skis recommended when any ski thread pops up :p.. Thanks in advance for help.
