Hey Rev-O,
Like Ex states, you can drill for full rollers on the Morpheus cores without a problem. Only thing to remember is to watch where you place the mass bias. I drilled a few of them and I kept the mb on the right side of the grip while keeping the pin on the left. I drilled one with the mb on the same side as the pin and it rolled earlier.
There's also the max flare drill which places the pin 10 1/8 from grip center with mb at 3 3/8 from grip center. This is an old layout though, I haven't tried this one yet on a Morpheus. You might want to check with Brian or Del to make sure this is still a useable pattern on our core. Hope this helps...
Good luck tomorrow and represent, the Crew's behind you bud.
