I may be completely off base, but I would recommend that unless you have a genius for a driller, use something else to drill a Rico.
The reason I say that is that Hammer marks the No Mercy in a way I can't fully grasp. In order to get an aggressive, high-flaring and powerful drilling on that ball, Hammer recommends putting the MB in the track, rather than where just about everyone else suggests putting it (i.e., thumb-positive quadrant between the thumb hole and the VAL).
I've been drilling balls as a hobby for just a few months, but I've been shadowing professional drillers for years and consider myself to have a decent working knowledge of things, and to tell you the truth, I wouldn't drill a No Mercy for myself with a Rico pattern because I wouldn't be confident I was actually doing it according to spec.
Someone else may tell you different, but that's my opinion on it. I'd start with something more conventional for a Rico drill (I have drilled a Thunderstruck Solid and Thunderstruck Pearl with Rico drills). Use the No Mercy to try out your Sarge Easter grip and get something else for the Rico.
JMO.
