Yeah the table tennis and badminton are always fun (but do always make me bemoan the decision to choose golf and rugby sevens over squash for inclusion at the next Olympics. Rugby is a great idea, but golf? The Olympics isn't the biggest event out there for golf but it absolutely would be for squash).
I remembered really enjoying canoe slalom last time round and it is indeed still excellent, for the same reasons as skiing I guess, great physical strength and superb technique needed but to get the best times you have to take risks, so there will always be a few complete cock ups or dramatic moments when someone completely tears up a specific part of the course. Love it.
