Well, if it's not too late, keep in mind that the Ultimate is already a smooth arching type of hook, and with your slightly slower speed you might find that the Rico does not retain enough energy for you down lane.
I for one, have started using extra holes in most of my stuff, but the Ultimate is one that has always rolled better for me with no hole. So, I would consider a slight label shift that requires no hole (can be added later if a slight reaction change is needed). Keep the pin further up than Rico, and somewhere around 4 1/2 to 5" from you PAP.
