They will take a super edge and fly superb. They will do fine for deer if you do your part. Not junk, however there are better heads and way more heads that are worse by a long shot.
You are right about them being common, some versions more so than the other versions. The Hilbre and Bowlo shared a great feature....the inside of the ferrule was threaded so they could screw on and off a wood shaft, no glue needed.
