I want to purchase anyone of these tricks, along with Regeneration by Blake Vogt. His published wire tricks are: Splicer, Vintage Holdout, Marbles/Popout, and Fontaine.
Well I mean it all depends, all this tricks has it ups and downs. I'll list down the pros and cons
Vintage Holdout:
Pro: Has many applications that can be applied
Con: It only works with Vintage series deck
Marbles:
Pro: Again very versatile and also very visual
Con: Super knacky and difficult
Fontaine:
Pro: Visual goodness and probably the coolest sandwich routine that can be applied to anything
Con: It's knacky and it will hurt your fingers after awhile.
Splicer:
Pro: You get two visual color changes
Con: Haven't bought the product so wouldn't know the downsides
Anyway which ever one you get, you're going to have to devote a LOT of time perfecting it and making it look the best it can be.
