As I get older, I am less and less a fan of the roundhouse kick. But that's just me.In the Longfist style I practice (YMAA) there are I think literally no turning kicks/roundhouses - I come from an ITF TKD background and I asked about it specifically - there is a type of quarter the angle (in terms of knee angle in relation to the ground) kick, but it is designed to be done upwards at the base of the rib cage.
Then again, certainly rear leg roundhouses expose the groin for a good bit, and in the style there seems to be a major emphasis on always protecting that area.
