Every bow has stack. So lets be realistic! Without stack you have no energy, energy drives the arrow. Stack is relative to what you are willing to tolerate. As for fingers and pinch there is always some form of pinch, again the string can not be pulled back without creating some degree of angle. The less that angle the smoother your release can be.
That is great you like 58" and it works for you and what you are willing to tolerate.
Yes the Satori comes in 17" 19" and 21" riser and short, Medium, and long limbs. So you can tailor it to your liking.
