I always ended up with a bitter, nasty smoke when I kept my rh at ~70. Also had constant issues with cigars going out. You draw harder than I do, I'm sure of that since my cadence is primarily tailored to pipes so I wouldn't expect you to have the same burn issues. However, my cigars (and pipe tobacco too for that matter) all taste much better to me when smoked more toward the drier side. Long winded way of saying 'try dropping your rh to ~ 62 to 65 and see if that helps'.
