I wanna buy a second pair of Hex limbs, preferably Hex 6 because now I have the Hex 5. All I see though the last month for sale are Hex longs. My drawlength is 27" and I will mount em on a 17" or 19" riser. So I currently have short limbs and I am really happy. Should I buy the Hex longs or they wont work at their most efficient range for my drawlength?
