My recommendation as well - do some research!
Rhum agricole is wonderful (including the St George, specifically), although it is so different from molasses-based rum ("rhum industriel") that the first time is a shock, for sure.
Also as pointed above, the agricole that a lot of people use in Mai Tais is an aged one. Aged and and unaged agricoles are both funky but have very different profiles and are not interchangeable.
In any case, if you are trying to reproduce "the original Mai Tai", Martin Cate's research revealed that the Martinique rhum component was a molasses-based rum, not rhum agricole.
