i drilled my dirty bomb label and it worked great...then i got the hybrid and drilled it label too, and the reaction was very different...went too long for me..i drilled another hybrid with pin under and cg out, and what a difference,,,strong to the pocket..i would suggest you keep the pin below the bridge and see how you get on....
