I can't speak from a bowyers point of view on Trent's bows but I do own one. I met Trent at ETAR last year for the first time after talking to him several times over the phone. He happened to have with him the exact bow we had talked about. He let me shoot it a couple of times and needless to say I couldn't leave ETAR without it. I did feel a little bad because he said he built it as his personal bow for the upcoming year. I shot Every bow I could get my hands on there and his IBEX was by far the smoothest, fastest, and deadest in the hand bow I've ever shot. For those on his 2 year waiting list their in for a treat when the wait is over.
I do agree with Flem, with some effort and 2 years of practice you could probably build something that would look the same. But Trent has figured something out with the feel and performance that I haven't found in any other bow.
