In reply to Reach>Talent:
Beiersdorf Leukotape.
Expensive but excellent. It is absolutely non stretchy but can still be torn lengthwise or across, and becomes more sticky when the roll gets wet or damp while most other brands lose their adhesiveness. It will even stick reasonably well on sweaty skin. I have been doing judo for 40 years, where taping is even more crucial, and found nothing better.

edit: Forgot to add, the best cheap alternative where stickiness is less of an issue (because you tape large areas, e.g. the outer layers of a tape glove) is Intersport Hockey tape. You can buy it in Sweden in the ice hockey department of every sports store, and in comes in 50m rolls or so that you can find for 30 to 50Kr. I buy a couple of rolls every time I go hiking up North.
