James,
I had the pleasure of shooting several of his SS at B;more years back when Kirk first brought them into existence
I was shooting well past my comfort draw weight with that design.
As already posted, Kirk is the person to ask. Each bow has it's own personality and he shoots and finds a "right" brace for each one, so trust what HE tells you!
You will not be disappointed. I have a deposit on a set of the SEMI-Static limbs for my Sas LB and will get my riser to him directly to have them custom fitted.
I'm dropping weight (Again) and due for another round of rotator surgery this summer, so may need to hunt those lighter Semi-SS limbs this fall... I have seen the performance #'s and they're impressive at any weight!
