Befor fly rods were use I used 1/2" PVC conduit it bends very easy and very reasonable. In hollow walls fishing down from the attic I used jack chain. I have also used the coat hanger that was filed in a angle as it would not grab the carpet. On angled runs I used two fish tapes and the twisted one till it rapped it self around the other one then pulled gently till I pulled the other one out the hole. Great tips
I too would be lost with out that continuous link chain:D
The fly rods will work great in walls with blown insulation....
Thanks for the tips, I think I'm going to look into getting a fish tape.
