I recently picked up a treehopper drill and some grade 8 bolts. After much research on this thread and conversations with folks on saddlehunter.com, I have found the best climbing method for me and I believe the most compact carrying system for bolts. I just wanted to share for anyone else who is looking into bolts and the treehopper drill. It is a cell phone holder that is molle compatible , I will post a pic of it from Amazon.
