One or two piece driveshaft?

['65 chevy lover]

After much flip flopping between a TH350 with lockup and a 700r4, I finally got a transmission ( TH400 with short tailshaft ) and, need opinions about a driveshaft. Obviously, I want the strongest DS I can get. I'm wanting to know if I should try and go with a two piece DS or, go with a one piece. The truck is a '65 longbed and the motor is a 383 stroker with 450 HP and 454 ft/lbs torque. Current setup is two piece with carrier bearing and the carrier bearing mounts using inline bolts ( not u-bolt style ). I understand that one piece DS is most likely stronger but, not sure if it will work with my setup. Truck is slightly lowered ( 2-1/2 drop spindles front and, 2" lower springs rear ). Thanks in advance for any help. I would really appreciate it!
