I'm considering buying a long riser Robertson Vision Falcon (and already have a short riser). The limbs are interchangeable. What is the change in poundage by putting the limb from the long riser (57#) on a shorter riser, and vise-versa? The limbs on my short riser are 51#s.  Thanks!

Figure around two pounds per inch gained for every inch shorter and vice versa.

Thanks for the quick response!  Love this forum.

No problem, just be sure to post pics when you get it.    :D
