Green 2H question - Mith 2hander / Dark Reaver

[Seducio]

Assuming we are on Green:

At the high end say level 49 and level 50 is it worth it for a Shadow Knight that is wielding a Mithril 2-hander to swap in a Dark Reaver for the proc: Steal Strength every 9 min and once it procs to swap back to Mithril 2-hander?

What kind of dps diff would we be talking from the 27 Str difference w or w/out this Dark Reaver proc while wielding a Mith 2h?

Appreciate the input of some seasoned SKs if weapon swapping like this makes sense to do.
