Glad you asked. I picked up 2 versatrak downrigger mounts from Phison engineering in the U.S. solid machined aluminum, works great and the versatrack takes it easily. Just a tip, if you are handy, you can use standard carriage bolts and wing nuts to mount pretty well any accessory you want to on the versatrack. Below is the mount.
Standard Rod holders are easily mounted with carriage bolts so dont bother buying the rod holder mounts.
