I agree with Ed, Ti punch is IMHO best with an agricole white.
The difference is in the glass and also in the nose. Of course other good rums can do the job (ESA or SLR are fine)..
If you want to drink rum in Haiti, ask for "clairin' but beware, it is most of time "home made" and very strong... much cheaper than Barbancourt, which is mostly for export. It is possible in France (elsewhere also probably) to buy another white haitian rum, sold in the "fair trade" shops, it is partly made by Barbancourt and I find it harsher than the B. white.
