I would highly reccomend the afterbangs, i bought them last year and im so happy i did. I live on the east coast too and i do both jumps and rails, and they hold up great on both. the topsheet scratches a little but its not enough to weaaken the performance of the ski. Get the Afterbangs!!!
PLEASE take my advice on this one, I have ridden and own both skis. I rode the salomon threats 2 seasons ago. I broke one pair within 15 days and the next pair within 4 days. I currently am on my 3rd pair, which I gave away to my brother because I refuse to ride them. Salomon threats are absolutely awful skis, DO NOT GET THEM.
This past season I bought the afterbangs. I ride mostly rails, and smaller jumps. I really like them. Super poppy for rails, they have been durable, and have a nice fun flex. A nice fun rail ski. If you are looking to hit big jumps, then I might consider a different ski, but for small jumps, buttering around, and rails, you can't go wrong with the afterbangs. I've been really happy with them.
