I like the Bitzeburger fletcher and also the J-8 from Martin (about half the price of the Bitz). I never cap dip arrows any more. It adds weight and extra diameter to the back of the shaft, shifting the FOC. If aluminum, I don' t even see the point in cresting unless one wishes to be able to more easily identify your arrows from other similar generic aluminum shafts. Wood is a different story, but I stain the cap and crest with Sharpies instead of paint (again, to keep the weight down).

Wraps work good, but as mentioned are expensive. However, it' s possible (and relatively simple) to make your own cresting wraps using your computer and vinyl sign material. Put together your own design - print it on the vinyl, cut it out, peel it and apply it to your shafting. Feathers and vanes stick great to the stuff and when refletching it' s a heck of a lot easier to scrape or peel the vinyl off your shaft than it is to scrape off the fletching glue.

Also... for most materials, I' ve found Lok-Tite quick set gel (little silver space-ship looking bottle with silver squeezing tabs on each side) is about as good a fletching cement for all type of shaft materials as was ever made. It' s readily available at Home Depot for less than 2 bucks, works great and makes it easier to lay a perfect thin bead on a fletch than anything else I' ve ever used.

Just some of my thoughts on this.
