Dave is correct.
Wodan, Blue Fire and Silver Star all offer front row queues. However, Euro-Mir, Eurosat, Alpenexpress, Schweizer Bob Bahn, Pegasus, Atlantica Super Splash, Poseidon and Matterhorn Blitz all allow you to ride in front row if you wish as they are not batched and you can go to any row. The only ride which wouldn't offer you a choice is Arthur due to the nature of the ride system. However, Arthur makes little difference.
There are also Single Rider queues on Blue Fire, Wodan and Arthur.
