I am definitely not the resident expert on all things logging. That said, Bandmiller, I much prefer the loose swinging hook, but, it needs to be shaped correctly to do what you want it to do. A new can't hook is useless to me. I also put the larger logrite hooks on the smaller log cant handle. If you look at the logrite hooks, they are cut on a bevel on the inside of the hook. There is no talon shape to catch or bite, and it won't release because it is too narrow and binds.
First, the logrite hook is a flat piece of metal. Once engaged in a log, it won't release easily. The " tip/hook" needs to be wide and tapered. A quick twist and the hook should fall out of the log. Also, the tip should be filed to a very slight "talon" shape, so it catches easily but still falls away. The hooks are heat treated so a file will not cut them. All they do is scrape the bark until it happens to fit in a spot and grab. Put your cant hook on a log and watch where in the curve of the hook contacts the log. It should not touch the log until you engage the hook.
I watch many guys use a cant hook to try to PUSH the log to turn it.
You have NO power to push. With a correctly shaped hook, I can roll most logs across the yard without ever touching the metal hook. Once in a great while, I may have to "toe" the hook to get it far enough under the log to get a bigger bite to roll a curved or stobbed log.
Timing of the swinging hook is everything to getting it to work correctly.
Also, I have absolutely no use for a peavey. They are for log drives on the rivers which don't happen much anymore. They slide off the logs for not having the metal "Heel" that bites into the log. It's a "yankee" thing.
No offense intended, just stating the facts and only the facts.
