There are different grades of electrical tape. Buy the good stuff, not the cheap stuff. It's thicker and works in a wider range of temperatures. It can cost $7-8/roll instead of $1-2.
For bar tape tips, although I tend to agree with what Park recommends, I think the site isn't complete, nor is it professionally done. I ranted about it a couple years ago. But the best way to fix something is not to rant about it, it's to do it right.

What's interesting to me is that the bar tape post is the most often viewed post in the whole blog, by a large margin.
