The only time we've seen the SP-445 film holders interfere with processing, is when the negative is loaded in backwards (we've had several customers admit to that.) That leaves very distinct vertical lines if they're using the original holders. Haven't had anyone do it (or admit it to us) with the new holders.
Besides, Tom Wakefield (on the facebook thread) spotted it in another image of mine. I missed it, since it's on the white part of the church.
