Although these decks are gorgeous, the "one odd pip" is sure to make laymen suspicious.
No, it isn't sure to make laymen suspicious. It's just playing cards. The regular Bicycle Rider Back decks aren't the standard everyone's used to seeing. You have thousands of cheap decks from gas stations, airlines, promo decks etc. On top of that, USPCC have themselves printed tons and tons of different designs. And that's just in USA, where Bicycle decks are quite common. Outside of the US Bicycles are quite rare, and for example in Sweden you're more likely to run into a deck of Öbergs playing cards. Does that make people suspicious of Bicycle cards here? Nope. Despite most of them not having seen them before.
The whole 'custom decks make laypeople suspicious' is just something magicians have cooked up in their own minds when faced with 'is that a trick deck?' while holding a deck of custom cards. It's not about the cards. It was either a) the spectator being the type of person to always think it's the deck, or b) you did something to make the spectator think it was a special kind of deck.
As for the odd pip thing on the Fulton's deck - it looks awesome and I'm absolutely positive spectators will only react with thinking that it's a cool feature of the design. They won't think it's a button you can press to make the magic happen.
To steer this even further back onto topic after my rant, I must say I'm looking forward to this deck. I went ahead and purchased a bunch after only seeing the box and the faces - still haven't seen the back design up close.
