Hello Moon,
This project is bigger than me so I will be looking for people to participate but first things first and that is to hear all the comments I can, to see if the changes that need to be made to satisfy the critics will not destroy the project.
I think the audience will be different than magicians and serious poker players. For them there is nothing like a deck like we have seen succeed very well on KS. This audience is for the traveler, the novice, the person who always wants something to do with their friends when there is a spare moment after lunch or waiting for the next project to start.
I am ruining yet another deck to experiment with hole size and position. The reason I chose the location for the hole was to accept the caribiner. If you make the hole it too far from the edge then the deck will not fall to the bottom of the caribiner but will become cocked and will scuff the finish inside the hole, which is all the edges of the cards. The other option is to change the carabiner size. They even make round ones so that is not out of the question. Yes, there could be different styles of trek decks for the different styles of people. One thing I noticed and you were right when you said the hole allows for some really cool art work.
The hole is unique.....except in westerns where the card is shot with a colt 44......hmmm, interesting video idea. OK, back to reality. There is the issue of copy right and patents which I hope could be covered from sales. Thanks to the changing rules in the uspto, once the idea is out in the U.S. and Canada you have 1 years to file. For me no problem, I just want to see if the idea will slide.
I don't want the hole to be used for a nail for another coffin project...... Don, that was a cool phrase you used a while back, hopefully you will not use it on this one. Only time will tell.
