I don't have much experience with logs, this is only the second one I've used. I picked this one up used at a very good price and feels pretty nice in the hand.

My pully system is made out of some 1/4" galzanived cable, some 500lb pullies and a loading pin. It works well for homemade.

I built one with "scrap plywood" when I was doing crossfit. I've cut open one side, added a shelf and some drawers and us it for storage now.

I use this for triceps work mostly, this thing just hits different.

This works well for my home made cables. It's easy to set up and break down.
