I grew up skiing on the East Coast, but I learned to ski the bumps when I moved to Colorado so my techniques may be a little different than you will have to use. I'm 5'9" & 165lbs & I find that skiing the bumps on anything less than 175cm is too short for a few reasons. The biggest reason is that when you need to slow down in the zipper line, you need to give a quick tail slap at the bottom of the bump to scruff the speed off. If I'm on skis shorter than that, then this isn't possible because there isn't enough tail. The same is true for the tips, whereas at some point, you may need to drive the tips down the frontside of the bump. Well if you do this with a short ski, your weight may to be too far forward when you begin to contact the new bump and you are going to do an endo.
Now if I was a perfect skier and skied every line properly, I'd be perfectly weighted, and would be never get going to fast and wouldn't have to use the above techniques.
For skis, you state they need to be both slalom & bump capable. So you'd want to find one that is medium flexing, not stiff slalom boards which tails won't abosorb enough. They will act like a spring and you won't be in the bumps too long. So give up some slalom performance and find a good flexing ski. If you are big person, than you can get a stiffer ski. One last thing for the skis is that a fat tail is not going to want to release you in the turn as one with skinier tails. Slalom skiing is carving, whereas bump skiing is more pivoting, sliding & following the ruts.
I know skis have gotten much shorter in the last number of year and much more shapely. This isn't quite the design that you want for a bump ski.
This is what works for me, so just weigh this with what else has already been written here. When all else fails, demo, demo & demo.
