Anyone else ever tried it? I did, lets just say it was hell. but at the end i was level 10. What is the lowest you have ever started it?

That sounds like torture! I've done it at level 8 on normal and that was bad enough

The reinforced sierra madre armor made a huge difference. I also picked up as many mf cells as i could find.

Do it on Dead is Dead.

So you won't suffer so long.
