The Acutrak and Tranz single cams are identical with the exception of the name that was etched onto them. Rytera did make the AX and Z with the Tranz cam
from 09-12. String should measure 91" and the buss cable should be 34" on the AX, and ATA was close to 33". Not really sure on the specs for the Tranz Z as I never
sold any of those.
I will agree that the Acutrak, Tranz cams are super smooth to draw, and makes for a real pleasure to shoot for extended periods.
