Wrist Mount...Psych Help Cabin Tutorial


Hey guys I was wondering is anyone could help me out with this trick from Charles Haycock. Its Wrist Mount…Psych.

Im having trouble at the part from 1:03 to 1:10 Where he swings the yoyo over then loops it and somehow ends up in a triangle.
I keep getting a knot or the yoyo winds up binding. I cant get it into the triangle.

Thank you so much to those who reply and help
