Foxwoods satellite - big mistake?

Fairly certain I'm gonna take a beat down for this, but pushing on certain flush draws seems to be a predisposition of mine.

205 entries, top 3 get 11500 packages, some cash for 4th - 6th...

We are maybe 10 minutes into the tournament and MP3 has been playing very LAG, so I was not surprised to see him call my 4x BB raise...I expected a call with most any two...

Interested in how this applies (or not) to general satellite theory where only a few spots pay off - seems like I needed to get chips early and this seemed like as good a spot as any. Contrast and compere with the whole "put your tournament life at stake" and I'm left with a big idunno.

In the end, pushing on what is at best a coinflip and maybe worse makes this feel like a bad line, but I struggle with "pulling the trigger" to get deep. Help?
