Diffferent Humidity for Different ISOMs??

[fishy]

With the arrival of the wet weather in Seattle, my humidor is tending to run around 70%, in contrast to the mid-60s in the summer. I am finding that some ISOMs, particularly Partagas and H Upmann, seem to burn and taste fine at this humidity..but others (Bolis in particular), seem to burn poorly and taste sick. Anyone else have a simlar experience??? Any recommendations on how to keep the humidity in the mid-60's when the outside relative humidity is 100%! .
