Baba au Rhum: Why am I not getting a good rum flavor? I've been wanting to make these for years after having some really good ones in Paris. Now I'm finding these are hard to duplicate!

I find I'm not getting enough rum flavor. There is definitely sweetness from the syrup, and a bit of orange from the orange zest, but I can't add more rum to the syrup because there is already a cup for the syrup made with 2 c water and 1-1/4 c sugar. I tasted a sample dipping of the baba and it actually gave me a buzz! (Granted, I am sensitive to alcohol.) I read a thread about alcohol and how to burn it off, so I put the syrup in a wide pan and boiled for 5 minutes or so. None of the recipes I looked at (and there were many!) said anything about using rum extract but I wonder if that's a possibility. 

I don't know much about brands of rum, but I am using Whalers Dark Rum.

Does anyone have experience making baba au rhum, and if so, with what results?
How can I get a more intense rum flavor? 
Has anyone making these ever used rum extract?
Mmmmmm- I loves me a good Rum Baba!
I'd personally go with Myer's dark rum. In my experiences I've found Myer's Dark to have the best/ most intense rum flavor out there (yes, it's a little expensive).
I think boiling the alcohol off would heat the rum to a point where you're going to alter the delicious rum-ness!
Heating the rum a little and then igniting the alcohol vapor would suffice to eliminate the alcohol without disturbing the other flavors. Just be careful and if things take a turn for the worst- stop, drop, and roll!
