Career Advice -- Mid Office Small Chance at Trader or ER?

I am post MBA, don't have trading experience and that has been my goal the past 4-5 years but it is tough breaking. So I had a junior trader role lined up but it blew up in my face at the last moment so I've had to revaluate some things in the past two months. I have two options lined up. One is an equity research role at BMO Capital Markets. The pay is solid and it is a front office role. The problem with that is the trader path is essentially dead. Equity research is great but you aren't doing deals so you aren't going into PE. At best you make a move to a Equity LS HF.

Option #2 is middle office, listed as "Credit Analyst" the role works closely with FX/Derivatives/MBS traders which is great, but the work is due diligence stuff. Dodd Frank, counterparty risk, managing relationships for the sales guys on the desk, etc....Definitely more btch work which I would be willing to do for a couple years if it could land me in a trading role. The guy who is leaving moved onto the FX desk in a sales role.

I have no outs left to play so the fear is getting stuck doing middle office work forever (jump out the window right now). Doing equity research is certainly better than that but that would essentially be giving up on the dream of trader. Safe play is ER, but I doubt I'd be able to give up on the trader dream unless there is literally no chance it could happen.
