I am one +1 for tinctures with rum, but agreed that you can get good to great results with both methods mentioned. I think there is limited risk of infection as long as it is a normal gravity brew and the beans are kept well. If you would be willing to eat it, you should be willing to put it in a primary/secondary. The yeasts do a good job of providing a healthy atmosphere once it has reached AA%.
Good luck on your brew! post your selected method/results/reviews for us to see.
