Iksar SK weapon question.

[ScottBerta]

My primary alt is a pretty well geared 60 Iksar Sk.

He currently uses Greenmist and I enjoy the weapon because of the proc and stats it adds. It also allows me to use a shield which add more stats and provides me with ability to bash. However it doesn’t do a great amount of damage. My question is would getting my actual SK Epic (would have to buy LR for 75k part) actually benefit me (all around) far more than using my Greenmist/Shield? Would cost justify the potential upgrade? It should also be mentioned I don’t raid, I mostly will just duo that char in sebilis or other zones with my brothers few lvl 60 chars. Mostly duo my Sk with enc or shaman.
