Gold Shortbow and Curses Staff mod

Hey all

I was hoping for a price check on two items.

The first:

(Gold)
Icy Shortbow of Marksmanship
Cold dmg 15-28 (req 8 marksmanship)
Damage +20% while hexed
Marksmanship +1 (20% chance while using skills)

My question is, I know it's worth a lot more the icy upgrade if I salvaged it, but would it be more than the marksmanship upgrade? I'm no good with bows; never had a ranger, so I never got to know the market.

The second (which is harder to PC, I know; I just want a guess):

Staff Wrapping of Curses +1 (20%)

Weapon Mods Baseline Prices: http://www.guildwarsguru.com/forum/s...ad.php?t=44867

Curses wrapping: ~20-30k imo

whats the req? salvage if high, couple k if low
