By USBC standards, it doesn't need a hole.
But without a hole it is not a Rico drilling and will not react like one. It makes no difference in today's balls, if you drill the weight hole and it has 3/4 ounce of negative weight. I've done that many times, the balls still hook, like crazy. If you want a Rico, drill it like a Rico.
Yes, not putting the hole there reduces the flare potential that is part of the Rico dynamics. Put the hole at 6 3/4" where it's supposed to be.
