Average iLevel to start 25man raids?

[Pelleas]

Average guild (we killed LK in 10 and 25normal and a few heroic bosses, that's it).
What is the average ilevel you guys think we need to start raiding in 25 mode? We are thinking Halfus.

340? 345? 350?
I don't want to start undergeared and some exceptional players might be able to kill him in 333s but, we're not that great
Many thanks

Full Heroic Blues or better.

I Think the avg item level for entering raids is ~346ilvl.

If you have most of the loot available through heroic 5-mans, best gear available via reputation, as well as crafted epic gear, then you're definitely set to take on Halfus. I guess that would make you 348ish average item level.
