The video below contains both a TH9 Logowiwi and Hogowiwi attack. The former showcases how to use back end loons on top of the Gowiwi attack whilst the latter how to use mass hogs in conjunction with the Gowiwi.
It is also possible to Logowiwi in the same style as the Hogowiwi but using back end loons can be a more controlled and accurate attack.
