There should be at least 5-8 shoots coming out of the node. They usually grow 2-4 per year, the strongest will be the 3 year old cane. 2 year old also works great, it is a lot lighter than the 3 year old cane. I carry a 3/8 or 7/16 open end wrench and a 5/16. If the 5/16 doesn't fit and the 7/16 does, I cut it. Using a minimum and a maximum gauge makes your shafts a lot more uniform. I use the 3/8 for bows over 50#, 7/16 for lighter bows, there is overlap. I personally pick the cane with really long nodes, but that is personal preferance. Bill
