If the rh is that high, I would let it rest for a few weeks. My b&m stays around 65-67% and the customers have noticed and commented that they seem to be enjoying the cigars more when they smoke them at purchase than in years before.
Personally, I think the LP9 is very, very similar to the Mombacho Thermonuclear and the Mombacho is quite a few dollars less and not such a jawbreaker.
