I use a KU grab-it and lashing strap and it works slick with very little weight. A number of hunting guides have commented that my set-up is the best they have seen for carrying a bow of the many they have seen. The KU grab it has a different spacing for the bottom attachments so you need to stuff the 3 bar sliders though loops on the bag rather than the rectagular plastic things you would normally use. This works on the Highcamp bags, but I cannot vouch for the Timberline. I attached the lashing strap to the highest loops on the side of the frame, and you will want to tighten the lash strap and then connect/tighten the vertical straps to hold the top pouch tight over that to keep the bow from moving side to side.
