Solly: Airstrafing, triple/double syncs, surfing, pogo/speedpogo.
Demo: any jump that doesn't start with a double or more.
Except for all the maps that use tiny head-height or even crouching corridor connectors that you can't speed pogo or wall jump through and just end up being annoying and slowing you down. Would rather have teles than those most of the time.
