Which has better mobility without Bi-Swing Back and Underarm Gussets? Aero Sheene or Aero Board Racer (and BR J100)

[mippo]

I'm thinking of getting one of these leather jackets in the future. I prefer a jacket with good mobility without needing a full bi-swing back and underarm gussets/footballs.

Among these 3 jackets which one would give me the best mobility when I need to reach my arms forward and upward? Would the mobility be as good as a jacket with full bi-swing back and underarm gussets? Is it still comfortable if the mobility is good?

I would appreciate everyone's advice. Thank you.

This is an obvious no (which I’m sure you know).

That said, the Board Racer pattern, if worn one size up from your chest size, has good mobility due to the high armholes. Better still with bi-swing shoulders, of course.

Boardracer in a softer hide. The Cafe Racer pattern aka the Sheene benefits from a full action back.

high armhole and pre rotated shoulder give best mobility

@navetsea
I think I mostly understand why higher armholes (up to a certain point) give good mobility, but could you elaborate on the shoulder rotation? Ideally with pictures/examples. I think this topic was touched in the Field Leathers thread as well.

Also if possible maybe someone could post a photo with a short description of each mobility solution? And maybe compare them, pros and cons. Shoulder gussets, full action back, bi swing back, underarm gussets...
Thank you in advance!
