Where are ya'll ordering your supplies from? Fiber Glast is one of the most expensive sources for fiberglass or carbon cloth. CST may be the only supplier to top them.

Solar Composites generally has the best pricing on carbon cloth stateside. ACP has good pricing on sleeves: http://www.acpsales.com/Tapes-and-Sleeves-c-4957.html

Tape can be made from sheets of 5.7oz carbon, I do it all the time. Sleeves are much better for tube type repairs, simply because they are easier to work with. I've repaired 3 hockey sticks and a myriad of broken carbon tubes in the past few weeks and most all were a 30 minute job with the sleeve, and all came out stronger than the original tube.

On this, I will suggest you use super glue (thin CA) to bond the stick back into shape. Epoxy would do OK but CA dries instantly so if you can get a second person to apply the glue while you hold the joint in place it will work perfectly (CA is near as strong as epoxy but more brittle in this application). Then scuff the surface with 150 grit paper and apply the sleeve or tape wrap with epoxy. Use Jake's and/or Bille's suggestions above for wrapping with peel ply to get a good finish. Clear tape can be substituted for peel ply in a pinch but is likely to stick to the mess when you are done.
