Its hard to recommend, cos different things work for different people.
But remember Hickory IS the most widely used wood for Drumstick manufacture.
I have always played hickory, and i did switch to Promark 747 Oak for a couple of weeks when i playing nightly cos i wanted the durabilty. But my hands suffered from the increased shock i was getting from the stick, so i had no choice but to switch back.
Another option is the Ahead Sticks, which are shock absorbing, AND last very long (in most cases). But they have too much flex, thus feel pretty different (and sound different too) from wood sticks.
In the end, the best option might be to just stick with hickory, but try
different manufacturers to see which one holds up best for you.
