You stated the transformer was 125-0-125....meaning it has a center tap. Therefore only the last two pics, full wave, NOT the bridge ones apply.
Choke input will get you lower voltage, more current, and better regulation (less difference between peak and average output voltage).
Bottom line is the highest voltage is going to be cap input and even with solid state diodes only about 175 volts.
