Curious: difference between a WD hitch and Hensley Arrow

HA is a very good hitch and controls sway very well. Unfortunately there are several parts considered wear parts. Those parts wear quickly and can cause other problems. For some reason I had lots of problems connecting the hitch to my TV. It was so frustrating that I sold the hitch with the trailer. I know I don't want any more and other hitches can do the job in a perfectly acceptable manner with much less care and feeding.
