The big issue is those big curves put a tremendous amount of twisting pressure on the limbs. Border gets by by using a special carbon on the belly of the bow and they state that what the maximum draw length the bow is warranted for. If you check the FD curve for the Border super curve and compare the amount of stored energy that is transferred to the arrow you will find they are inefficient due to the wasted energy lost in the mid limb flexing during the shot from being overpowered by the big mechanical advantage the big recurves have. Not worth the effort unless you like the feel of the draw cycle.
