I am familiar with Blaine/Harris's Strange Travelers, David Solomon's Thought Across cards and now
Harlan's Red Rover. I would recommend all three as I love them all but Red Rover is the best of them
in my opinion.
Red Rover and Strange Travelers are equal in their ease of execution but
Red Rover's gimmick's allow for a cleaner looking presentation and has some added things built in to
be more convincing and fair.
If you are looking for an easy cards across effect that looks
killer and uses minimal sleight of hand this is the one.
Incidentally Gary Jones has a
really nice non-gimmicked any deck version of thought across cards that was in Decembers penguin
magic monthly. Check it out if you can.
