Here is some bad advice.... but this is what I would do:
You like that style ski, you already have them in your possession, repair them the best you can and ski on them.
I myself searched ebay and looked forever for a good pair of Ten Eighty's and my purchase arrived with some terrible damage but I kept them and love them. Of course on my skis the damage was on the sidewall and top skin- your skis are basically shot.
Who cares- try something using clamps and the very best two part epoxy you can get your hands on; it probably shouldn't be the crappy 5 min. clear stuff either.
Keep in mind the damage just to the tip won't effect your skiing but it needs gluing. Clean out the dirt first and clamp it.
Now the cracked edge is about the worst I have ever seen and more than likely after you repair it- it will probably split again.
But I would try something and take them out for a run! That's just me.
Do your epoxy and clamping repairs before you do the p-tex repairs and tuning of course.
You might want to drill in (3) or more places (red) to load up the epoxy in there (and to help clean out the dirt first). The theory here is that the industrial epoxy will be adding strength, and not weakening the ski. I would knock down the sharp edge of the crack (Yellow). You will have a divet in the edge but this could help prevent it from snagging when the ski flexes and exposes the crack. In fact if you have a dremel maybe treat the split edge as if it is a cavity!
Once the epoxy and clamping is completed at the cracked edge; maybe just dig out a little more of the crack with a dremel tool and fill in the divet with p-tex as you fill the giant crater in the base next to it.
If you intend to spring off moguls with these junkers then you will be wasting your time trying to fix them. But if you do your best on the repair and take it easy on them- skiing casually- just cruising and skiing on soft conditions- heck you should be able to get in some runs on your favorite skis after-all!
And after a couple of days of skiing on these you will have gotten your money's worth out of them.
Then hit the moguls full throttle on Day 3!!
