FWIW: I've had no trouble at all using the same SCA-to-narrow adapters in Indys, Indigo2, Indigo, external enclosures...  Once upon a time I bought a batch of at least a dozen of these things so I'm using exactly the same adapter everywhere. Of course, in theory at least, there could be a flaw in them that only trips up the Crimson.
