why does the method really matter?
its the effect that matters. if you want effects where the method is cooler than the effect, you are basing your ideas on the wrong premise. lets say what you think the method is is the correct method, then so be it. if you think its a cool effect just get it. if not, come up with something better. ref4m isnt ment to be the end all of tnr effects, it is an impromptu TNR that you can do when ever you want to do one. if u want a great tnr, look maybe at torn, thats a great tnr with a great ending too, but if you are looking for coolest method, get TNR from T11, thats a crazy method.
You need to evaluate the effect on what the effect looks like to spectators and what you want it to accomplish, not by method.
Jay Sankey has some crazy nice effects for laymen, but as magicians, we pass most of them up because they are too simple for us. Stop thinking like a magician and start thinking like a performer, or a laymen, what is the effect as a whole in the eyes of the spectator.
Now to answer your question, you are probably right so if that is all you care about, dont buy it. I personally think its a nice clever method, which has been done in the past, but taken a little farther. But i personally dont think that you will be dissipointed if you pick it up. Im sure blake is coming out with some more awesome stuff that i would personally save my money for, but that is just me.
hope this helped a bit and i dont mean to sound harsh, but i feel that the ends justify the means.
