Hi Luis, glad to hear you are looking to add a TK to your line-up!
I have heard nothing but good things about WTF. I'd suggest checking out the vetter armor makers thread, here, as well as WTF build threads in the Build Thread sections.
Furthermore, I highly encourage you to research and consider the Expert Infantry/Centurion programs, as you'll have a much nicer suit as a result (and bragging rights).
