Really depends on the carbons that you are fletching. For Easton carbons (MFX, Axis, Bemans, ect...), superglue is the best. Platinum does not hold longterm. The draw back to superglue is cleaning the shaft off when refletching them. Superglue is a pain to remove.
CX, GT, AD, and any carbon with wraps install you can use bohning platinum. It holds good and easier to clean off and refletch when necessary. If I can avoid it I won't use superglue on my personal shafts just becuase of the pain the it is to clean and refletch them again. dino
