Ranger DPS DW vs 2handed

[damstraight4]

I'm a 39 ranger. I've seen on the forum "Buy Woodman's until epic GG". I was wondering if there are cases where dual-wield might be better.

Do I get more procs with DW for Call of Sky? Is Call of Sky dex based?

I know if I spend a ton of money then DW might be better. For DW I have a 12/22 velium 1hs, and the velium brood axe. I'd be willing to spend a couple grand to get a new 1hs if it meant better dps.

What do you all think?
