I feel that J's and 10's are the hardest pocket pairs to play. If you're low-stacked in a tournament, you're really left no choice but to go all-in with them.
If on the other hand, you have right around the average, you should probably play them just like you would any other middle pocket pair. Myself, I usually raise with them pre-flop instead of just limping, but will just call with them if facing a raise pre-flop. That way I can get away from either hand if an over card hits on the flop.
