Tech is a good razor to develop your technique. Put a blade in it, any blade, and use that combo for 6 months. Learn to use it. After that time, if you consistently get great shaves with it, a) use that combo forever (yeah right, this IS B&B afterall), or b) change one variable at a time (blade or razor or brush or soap) and gauge the result. This way you will slowly but surely work your way toward your optimal shave.
