From an earlier post from dgg45:
Pechauer grows their own trees, processes the lumber in their own mill, built a machine shop and makes all their own joints, screws, etc. What custom cue maker can top that?
I don't know about "best", as I think that takes many years to establish, but I have tried several cf shafts, and yet still play my pechauer wood shafts. I'm old school. I prefer the look, hit, and feel of wood shafts. Just a personal choice...although the low deflection laminates are nice too.
