I just got done watching the first ten minutes or so of a video that teaches you to perform the invisible deck with a regular deck of cards. (If you don't know what an invisible deck is, stop reading this right now and smack yourself in the head with the keyboard)
I don't understand why anyone would EVER want to do the ID with a normal deck. I don't care how much you boast about how yours is clean or better or whatever. Read this next line slowly: YOU CAN'T IMPROVE ON A TRICK THAT DOES THE WORK FOR YOU! This is like someone saying, "Well the wheel works alright and all, but I bet I can make it better." Leave well enough alone you silly gits!!
If you really want to buy a video that teaches you to do the ID deck better, I mean if the urge really is that strong to spend money on something, find something that will teach you a good deck switch and go from there. If you really have to complain about carrying around two decks of cards on your person, then you are in the wrong business my friend. Maybe being a mime is more your speed.
So my tip to you is don't be fooled into thinking you need to improve upon something that doesn't need it. Chances are the thing that needs the most improvement in your magic career...
