i use the nash fang mainly i find they stay sharp unlike esp raptors they go blund easily also the korda widegapes are very good as well as the longshanks:D
i tend to use a hooklink about 6 - 61/2 inche long i found perfect but if am having weird bites will go down inche or two because the fish might be getting away without being hooked. :D
the trouble is with the raptor they don't stay sharp and tend to bend at an angle but have had no problems with korda hooks wide gape, nash fangs , gardner muggas:D
i use the stack rig with corn one grain of pop up corn at the top three real pieces in the middle and one fake grain on the end it is then criticaly balanced. :D
