I have several click wrenches 1/4", 3/8" and 1/2". I have one 1/2" flex wrench with an analog scale that comes in very handy and two 3/8" wrenches with an analog dial. I use all of them for different applications. A 3/8" and a 1/2" should take care of your needs quite well. I use the click wrenches when tightening bolts/nuts in places where I can't read the analog types. I like the analogs because they give a smooth even torque.
