Hey guys,
I found the best shipping tube last week. It's a piece of 4" triple wall drain pipe, Lowes and Home depot carry it. It's as light as cardboard tube and much stronger, and $8 for a 10' length makes it affordable. Plus it can be used for arrow storage after the bow arrives, I used a piece wrapped in camo denim for a side quiver.
I shipped my trade bow today, maybe we will see some photos of the bow in action this weekend.
