Hello David!
Welcome to the forum! I hope that you will visit and post often.
The highline inner wrist engagement does not offer as many possibilities as the outer wrist engagement, and you have to be a bit more creative! Both lead and rear hand jut sao can work. Pak sao w/low hit can work. Huen sao/pak sao can work. Huen sao/lop sao can work. Pak sao/qua chuie can work. There are a few others, but these are the most used.
I have two seminars a month, four training camps a year, two Instructor's Conferences a year and one week long Aprentice Instructore Camp a year at my school. Anyone with a serious interest is welcome to attend!

Keep Blasting!
