Im not ready to shell out the cash yet but i see it in my bear future, ive been doing research and im on the fence between the Centri or TVS as you are. Ive had a Roots charger and its awesome! all that torque comes on in an instant! but they rae more prone to heat soak and are liquid cooled. What makes me think im gonna go Centri is my friends argument for them, Usable power, the TVS give you peak power at such a low RPM that traction becomes a serious issue, yeah its fun on the street but thats exactly where it gets heat soaked. The Centri will gradually kick in so you can put the power down better, Centri's are more efficient and do not heat soak as fast but you have to wait for red line for that peak power, Centri's are also a bit cheaper.
Although the Eddlebrock seems like a great product, there was all this hype when it was about to come out and now all you hear is crickets, i dont think it lived up to its claimed potential, dont see a lot guys running them either. After seeing a bunch of TVS set ups, i think Kenne Bell is a suprior design.
