Yea, I think it all depends on how much you want to leave to chance. I had time and I didn't want to leave anything to chance. Other people didn't, so they struggled on my day while I prospered but today seems to be different. That's the nature of this test because it is a very much a risk/reward type system. You can forgo studying O.Chem and HOPE you get something like today but if you get something like I did then you will get slaughtered. Same with some other topics like digestive enzymes. If you master everything then you won't be surprised by anything, but if you are low on time (like I just realized you are) then you have to take some risk because you can't fit everything in.
I think it's a personal choice, you should review organic and to what extent is up to you. You said it's a strength so maybe TPR with the shorter time would be a better route with BR passages but know that you will be acquiring some risk my doing that.
These test's don't follow predictable trends at all, I mean there is plenty of genetics/molecular material but other than that everything is up in the air. I wouldn't be surprised if tomorrow had 3/7 Organic and mostly physics. My point is that you never know so be prepared (or reasonably as you can) for everything. It's better to be prepared for a lot of different things rather than master one thing and be weak in others. The MCAT can't possibly test everything subject on test day, so they find 3 or 4 things per section and batter you with them.
With all that said, I think today was an outlier. To my recollection there have probably been 2 or 3 out of 22 dates in the past year with just one organic passage. My test had plenty and I think the two Jan. dates had 2 and 3 passages.
Also, the bulk of the difference between TPR and TBR isn't in content but in the answer explanations. The TPR chapters are about the length of TBR chapters (40ish pages per chapter for each book). By my estimation the difference should take you no more than an extra study day or day and a half to read TBR. The passages are good prep so you definitely should not skip those either.
Hope this is insightful,
