I've been using bamboo shafts from China for the last number of months. Bought in bulk for a fairly good upfront cost.
I'll explain my experience, and ask if you guys could tell me if this is normal or if I should give them another shot from a better supplier? Right now I'm planning on using up what I have and go back to wood.
Spines are relatively matched, but diameters and weight very quite a bit as one would figure for this product. Fortunately they are light enough that I can make my arrows match closely in weight by adding nails or wire to both ends to bring the lighter weight shafts up a weight matching the heavier weight ones and still keep around 10gpp. This seems to be working fairly good.
One problem I have is that maybe 10% are straight enough to make an arrow out of the box. About 40% are cork screwy enough that I am unable to make a shaft until my skill level with straightening improves a ton. Another 10% are cracked. After culling I end up doubling the cost of the shaft from $2 to $4. Not too bad compared to other shaft materials but considering I can get shafts from True Shaft for significantly cheaper and most importantly, not invest as much time prepping I'm not sure anymore if bamboo is worth it anymore.
Another issue I'm having is shafts splitting and shattering from glancing blows to 3D targets or pretty much anything that's not a perfect shot. Is this normal for boo? Or maybe caused by the suppliers processing methods?
I did try garden stakes but decided they really aren't worth the amount of effort for me.
ETA: I had a lengthy email discussion with the supplier and he assured me all of his customers are quite happy with his products. I did order a second time, and even after reminding him of our previous discussion on straightness and cracking I received the same results as above, 50% culled shafts.
