Hmm.. A dilemma, to be sure.
If you changed your first 50 based on other agents' comments that it didn't grab them in the 'critical early pages,' haven't you already surpassed that issue with the currently-hooked agent?
If this agent is already hooked, I would give them the rest of the original version and not complicate a good thing. If/when you get an offer from the agent, you can always discuss edits later. But that's just me-- oops, I forgot you weren't looking for advice! Haha, sorry sbp725.
