We happen to have a bunch of the 42t pulleys so we figured we'd use them. The 12t is 3D printed. Hopefully we will be testing it this weekend.

Ok. I put the numbers in JVN calc and it spat out 16.5fps free, 11.7fps loaded, but it loads at 37 amps at 8lb force. I guess it really depends on the load, as some measures will fall under their own weight even.
