Technically triangle laceration and brent stole are two entirely different tricks. Triangle laceration is based off of wrist whip while brent stole is just a laceration into a gt.
Also I noticed you don’t have a link for brent stole. Id give one but on my phone, so instead ill lead you in the right direction. Search beverchakus brent stole in youtube. Awesome tutorial.
Sounds like and extensive yet worthy project and I wish you the best of luck.
