I've seen a few tape jobs now, and the biggest problem I see with them is their insosnsitency. I've seen a few that simply pushed off the rim with minimal effort. That is scary. I have now seen one that was a strong bond that probably would not have come off under normal riding conditions. In general, glue is dependable and seems harder to mess up than the tape from what I have observed.
When preparing your equipment, you must always keep in mind that if you go down because of an equipment failure, there is a chance you will take others with you. I always try to have my gear over-prepared rather than under for this reason.
