Sascha’s Bridle/Centre cross modification

I have a different bridle on my magnets. Feels so much more controllable. Inputs are a little bit larger. Here are the meassures of the bridle:
Upper: 49 cm
Lower: 44.5 cm
Inner to Center T: 57 cm

I did Put the Center t 2 cm towards the Nose (52 cm form tip of nose). And let the bridle on the old position spine. This makes the backflip even deeper and multilazies and cyniques easier. This is my personal preference.
