torque converter builders

so it looks like ill be rebuilding (or having someone rebuild) the 727 this winter
while I have it out I want to go with a new torque converter, since that will be the last part that is stock

the car is a 71 duster, the drivetrain is a 360, build to a 408 with a 727 transmission and a 8 3/4 rear end with 3.23 gears

it is a daily driver


Ive been told to order a custom converter, but I don't know I should have build it
so far I have heard PTC, Dynamic, and edge
anyone have any thoughts on this, any experience, good or bad?

and maybe a guess on what my duster with full bench seat interior would weigh?
