first of sorry if anyone has problems with the accent, im from new zealand. cant help it

but whats important is u have to have good ankle flexibility and bigger feet is always a positive. be careful doing it against bigger guys as your knee can possibly be under pressure. the thing about it is though u have such good control that if ur knee is feeling strain you can just break him down to release it. ive never had any problems with it and my knees can be pretty problematic.
you can get submissions from here what u want to do is get your outer leg shin bone and rub it right under their gastrocnemius (big bulgey part on ur calf) u get it below there and u should be set but dont make it too low of course, then put the pressure on and hold it for a while, maybe try a few arm triangles from bottum or ninja chokes to distract them. dont expect an instant submission unless you have a good leg squeeze either. this is just a control with an almost submission, a bit like invisible collar. id warm ur ankles up a bit first just roll them around and it can be a bit sore holding it sometimes but were fighting here not making daisy necklaces so i think we'll all be fine.
apart from that give it a try and write up what u all think. theres a bunch more u can do with it than i showed there but my cell doesnt have much memory left. ive tried out twister with this and its worse than normal lockdown because of where the foot is he can just lift it up and is free but from half guard apart from being a bit harder to untangle its just the same stuff.
Have fun
