Major throwing techniques

There are a lot of throws in judo. Some are major techniques that are seen over and over again in competitions. Some are minor techniques that are seen frequently but are used to either get smaller scores (nowadays that would be waza-ari) or to unsettle your opponent and set them up for the big throw.

Then, there are the obscure throws like sumi-otoshi, uki-otoshi, yama-arashi and even hane-goshi which are almost never seen in competition. If those are worth learning it's only for historical reasons as they are what I'd call very theoretical throws which are okay for demonstration purposes but have no practical use.
