NL100 JJ facing 12xbb raise from multitabling set miner

[tubasteve]

This guy was the [censored] bane of my existence at the tables last week. He may be a 2p2er but I don't know. He had pretty typical set miner stats, although he seemed to loosen up a bit after this hand happened. I think he was at about 16/6 during this hand, and since I have him at 22/6.9 over 600+ hands. He was at 3 of my tables during the session so he probably had some kind of read on my play (I was playing fairly lag and very aggro postflop).

I hadn't seen him open for this much yet, but he was opening for more than the standard 3-4x+1bb formula normally.

I see arguments for folding, calling, and reraising preflop. What are my lines for various situations postflop for calling or raising?
